Introduction
Throughout its history, Diskeeper has improved with each new version. Diskeeper 2007 continues this tradition
with even more innovative new features and approaches to solving fragmentation problems for everyone, from
home users to the world’s largest enterprise IT departments.
The Diskeeper family of products includes Diskeeper Administrator. Diskeeper Administrator is not a
defragmenter, but an application that provides a single point of control by which you can centrally manage all
the Diskeeper versions 9.0, 10.0 and 2007 installations on your network.
Diskeeper Administrator provides very flexible policy-based management of Diskeeper in a network
environment. Key to this control are these network administration features:
ƒ
The PushInstall feature makes it easy to deploy Diskeeper to any supported computer on your network.
Need to install Diskeeper on a few hundred machines? Diskeeper Administrator can do it in a few mouse
clicks.
ƒ
Controlling defragmentation operations is simple, whether you’re managing a handful of computers or
thousands network-wide. You can establish policies that dictate how Diskeeper runs on one or multiple
computers at a time.
viii
Preface
ƒ
For ease of management, you can arrange the computers on your network into logical groups. Diskeeper
Administrator supports Microsoft Active Directory® groups, or you can create your own customized
groups. For example, you can easily set up different defragmentation policies, reports or preferences for the
computers in the Finance department compared to those in Engineering—or deploy Diskeeper to all the
computers on the fourth floor.
ƒ
Diskeeper Administrator provides a wealth of report and exception-based alert notification options
detailing the fragmentation on the computers across your network, and also collects performance and
reliability data that you can use to proactively maintain your systems.
ƒ
The Updates and Upgrades module enables Diskeeper Administrator to detect and deploy Diskeeper
updates and upgrades to all your managed Diskeeper computers. Note that an update is a no-cost
incremental version of a specific Diskeeper version number (such as from version 2007 build 100 to
version 2007 build 101). No additional Diskeeper licenses are necessary to update a Diskeeper installation.
An upgrade is a change from one major version number to another (such as from version 10.0 to Diskeeper
2007). You must own or purchase the appropriate Diskeeper license to upgrade a Diskeeper installation.
ƒ
You can use Diskeeper Administrator Edition to remotely-control Diskeeper 9.0, 10.0, and 2007
installations on computers all over your network. Without ever leaving your desk, you can perform any
Diskeeper task as if you were sitting in front of the remote machine.
About Fragmentation
As used in this manual, the term disk fragmentation means two things:
ƒ
ƒ
a condition in which pieces of individual files on a disk volume are not contiguous, but rather are broken
up and scattered around the disk; and
a condition in which the free space on a disk volume consists of little pieces of space here and there rather
than a few large free spaces.
The effects of excessive fragmentation are twofold as well:
ƒ
ƒ
file access takes longer because a file must be collected in pieces here and there, requiring several disk
accesses instead of just one; and
file creations take longer because space for the file must be allocated in little pieces here and there instead
of just one contiguous allocation.
The bottom line⎯fragmentation slows Windows system performance. The longer you wait to defragment your
disk volumes, the slower your computer runs.
With Diskeeper, all the volumes in a Windows operating system can be kept defragmented indefinitely.
Diskeeper cleans them up and keeps them that way. This includes volumes with compressed, encrypted and
sparse files on NTFS volumes.
Running either invisibly as a background process or as a manual defragmenter, Diskeeper carefully rearranges
files and free space on a disk volume so they consist of as few pieces as possible. Diskeeper runs when other
processes are active on the computer, so there is no need to lock users off a disk while it is being defragmented.
The end result: Your computer will run faster when Diskeeper is enabled.
Overview
1
Chapter 1
Overview of Diskeeper Administrator
Diskeeper introduced the concept of enterprise-wide defragmentation, and Diskeeper Administrator represents
the next generation of this technology. Diskeeper 2007 Administrator advances the concept of policy-based
centralized management of Diskeeper throughout your network.
With Diskeeper Administrator, you can install, control, and monitor Diskeeper on computers throughout your
network.
Here are the major features provided by Diskeeper Administrator:
ƒ
The PushInstall feature makes it easy to deploy Diskeeper to any supported computer on your network.
Need to install Diskeeper on a few hundred machines? Diskeeper Administrator can do it in a few mouse
clicks.
ƒ
Controlling defragmentation operations is simple, whether you’re managing a handful of computers or
thousands network-wide. You can establish policies that dictate how Diskeeper runs on one or multiple
computers at a time.
ƒ
For ease of management, you can arrange the computers on your network into logical groups. Diskeeper
Administrator supports Microsoft Active Directory groups, or you can create your own customized groups.
For example, you can easily set up different defragmentation policies, reports or preferences for the
computers in the Finance department compared to those in Engineering—or deploy Diskeeper to all the
computers on the fourth floor.
ƒ
Diskeeper Administrator provides a wealth of report and exception-based alert notification options
detailing the fragmentation on the computers across your network, and also collects performance and
reliability data that you can use to proactively maintain your systems.
ƒ
The Updates and Upgrades module enables Diskeeper Administrator to detect and deploy Diskeeper
updates and upgrades to all your Diskeeper computers.
ƒ
You can use Diskeeper Administrator Edition to remotely-control Diskeeper 9.0, 10.0, and 2007
installations on computers all over your network. Without ever leaving your desk, you can perform any
Diskeeper task as if you were sitting in front of the remote computer.
In a typical scenario, you would use Diskeeper Administrator to deploy Diskeeper Professional, Pro Premier,
Server, or EnterpriseServer to remote computers throughout your network. Then, you would optionally use
Diskeeper Administrator to establish policies that control the manner in which Diskeeper would run on those
computers. These remote computers can optionally be divided into groups—you can use your existing Active
Directory grouping structure or create your own custom groups. After establishing any desired defragmentation
policies, you can specify which alert messages you’d like to see, and how often you’d like to see them. At this
point, you’re done! Diskeeper will automatically handle the fragmentation throughout your network. At any
time thereafter, you can use Diskeeper Administrator to generate reports that allow you to easily check up on
Diskeeper operations network-wide—without ever leaving your desk!
Diskeeper Administrator consists of two main components — the Administrator Console and the Administrator
Database.
ƒ
The Administrator Console is the “control panel” by which you send commands to Diskeeper computers
throughout your network.
ƒ
The Administrator Database component works in the background to collect and store the policies and
properties, logging, reports, alerts and other informational data for all the computers on your network with
valid Diskeeper licenses.

Overview
Remember Diskeeper Administrator is not a defragmenter. In order to defragment the computers(s) it is
installed on, it is necessary to also install Diskeeper on the machine(s).
Other Useful Information
In order to start using Diskeeper Administrator, it is necessary to first configure the Administrator Database.
This includes specifying whether to use an existing SQL Server 2005, SQL Server 2000 or Microsoft SQL
Server Desktop Engine (MSDE) database, or installing MSDE locally on the computer running Diskeeper
Administrator. If neither of these are installed on your computer, you will be prompted to download and install
a free version of MSDE from the Diskeeper Corporation web site. The database configuration also includes
naming the database, and specifying where it resides. See Configuring the Database page 15 for information
about configuring the Administrator Database.
To gather the Diskeeper data from remote machines, Diskeeper Administrator must use login credentials for an
account that is a member of the Administrators group on the domain or workgroup being polled. (This account
information is also used by the PushInstall feature described on page 18.) Diskeeper Administrator allows you
to use different login information for each domain on which you want to control remote Diskeeper installations.
See page 16 for more information about entering account information.
After Diskeeper Administrator has found the other Diskeeper installations on your network, it can then gather
any existing defragmentation-related data from the remote machines. It gathers post-defragmentation
performance and reliability information about each individual computer and stores that data in the
Administrator database. From then on, any time Diskeeper-related activity occurs on one of the remote
computers, the Diskeeper Administrator database is updated, so information about the condition of the remote
computers is always instantly available. You can view reports showing either the information currently in the
database, or poll specific Diskeeper computers for reports showing up-to-the-minute information (including
data from computers that have been temporarily off the network—such as laptop systems).
Installation

Chapter 2
Installing Diskeeper Administrator
This chapter provides information you need before, during, and after installing Diskeeper Administrator.
Before the Installation
Platforms and Windows Versions Supported
Diskeeper Administrator runs on the Intel® x86 platform (including Pentium™ and compatible CPUs from
other manufacturers) running Windows Vista™, Windows Server 2003, Windows XP (all editions except
Home), and Windows 2000.
Important Note: If you are installing Diskeeper Administrator on a computer running Windows XP Service
Pack 2, be sure to visit www.diskeeper.com/sp2 for the latest information about running Diskeeper with
Service Pack 2.
Additional Software Requirements
Diskeeper Administrator requires either SQL Server 2005, SQL Server 2000, or the Microsoft SQL Server
Desktop Engine (MSDE) to store Diskeeper-related information. The MSDE provides local data storage and is
based on the data engine used in Microsoft SQL Server 2000. It is provided on the Diskeeper Administrator
CD-ROM, and is also available free of charge from the Diskeeper Corporation web site.
Diskeeper Administrator also relies on the Microsoft .NET 2.0 Framework and the Microsoft Management
Console (MMC).
The .NET 2.0 Framework provides the communication facilities necessary for the various Diskeeper
Administrator components.
The MMC provides a single point of control for system utilities such as Diskeeper Professional and Server
editions. The MMC is used as a central location for a variety of Microsoft and other third party administrative
tools.
Note: The Diskeeper Administrator setup process will automatically install the .NET Framework or MMC on
your computer if needed.
Resource Requirements
The disk space requirements for Diskeeper Administrator depend on several factors. On most systems,
Diskeeper Administrator will need 80 megabytes or less. Allow up to 450 MB of extra free space for temporary
files during the installation. If the Microsoft .NET Framework is not installed on your computer, this requires
approximately 70 MB of additional disk space. Further, your system may require a new or updated version of
the Microsoft Management Console (less than 6 MB). Finally, if Internet Explorer is not present on your
computer, some other needed files (hhupd.exe, 50comupd.exe, and wintdist.exe) may be added.
4
Installation
If you install the MSDE when you first configure the Diskeeper Administrator database, it initially requires less
than 70 MB of disk space, although as the database grows, the additional disk space requirements will increase.
Also, the MSDE uses the Microsoft Data Access Components (MDAC), which will require approximately 26
additional MB of disk space if not already present on your system.
A Note About Firewalls
As a normal part of its operation, Diskeeper Administrator acts as a server on your network. If you are running
a hardware or software firewall, you may see messages indicating Diskeeper Administrator is trying to act as a
server. These messages are expected; you can safely allow these events.
You may also be notified that Diskeeper Administrator is trying to access the Internet. It is important to note
that Diskeeper Administrator does not access the Internet (except when you specifically use the Check for
Updates feature), but it does use Windows mechanisms that may trigger these alerts from your firewall. Again,
these messages are expected and you can safely allow the events.
Installation Procedure—The Short Version
The Diskeeper Administrator installation is typically fast and simple. Here are the basic steps:
Note: Make sure you are logged onto an account that is a member of the Administrators group.
1.
Insert the Diskeeper Administrator CD-ROM into the appropriate drive on your computer. (If you are
installing from a downloaded file, double-click the file you downloaded.)
2.
Follow the screens displayed, answering the questions asked as prompted.
That’s it! It would still be a good idea to read “After the Installation” on page 5, but you’re done with the
installation.
Installation Procedure—The Details
Installation Overview
Diskeeper Administrator is installed by the SETUP.EXE program supplied on the Diskeeper CD-ROM (or
within the installation package, in the case of a downloaded version). The SETUP.EXE program:
ƒ
ƒ
ƒ
ƒ
ƒ
Confirms that you have Administrator privileges.
Determines which Windows version you are running.
Checks for sufficient space on the disk for the installation.
Detects and removes any previously installed Diskeeper Administrator software.
Copies the necessary files to the destination directories, updates the Windows registry, starts the Diskeeper
Administrator service, and creates a link in the Windows Start menu for Diskeeper Administrator.
Installation Procedure
Diskeeper Administrator can be installed from a CD-ROM, or it may be downloaded from the Web. This
procedure applies to both methods. Before you start the installation, please note the following:
ƒ
You must be logged into an account that is a member of the Administrators group to install Diskeeper
Administrator.
This installation procedure assumes you are installing from CD-ROM. If the Diskeeper software was
downloaded from the Web, double-click the executable file in the directory into which it was downloaded and
go directly to step 3.
Installation
5
1.
Insert the Diskeeper CD-ROM into the appropriate drive on your computer.
2.
The Windows AutoPlay feature automatically displays a screen that allows you to install Diskeeper
Administrator or choose from an assortment of Trialware versions of Diskeeper Corporation products.
If you have disabled the AutoPlay feature, simply double-click the Setup.exe file in the root-level folder on
the CD-ROM and follow the instructions displayed.
3.
Click Next when the welcome message appears.
4.
After you have read and accepted the license agreement, click Next to continue.
5.
You can choose a different disk volume or directory for the installation. Click Change and navigate to the
location where you want the files for Diskeeper Administrator installed.
6.
After making any desired changes to the file destinations, click Next to accept your changes. If any
directory you specified does not exist, a new directory will be created.
7.
If Internet Explorer 4.01 or higher is not installed on your computer, another installation program is started
and a package of necessary components is installed on your computer. Microsoft Management Console
(MMC), which is the interface for Diskeeper Administrator, requires these components. These components
are a small subset of Internet Explorer⎯not the complete Internet Explorer product. Installing these
components (hhupd.exe, 50comupd.exe, and wintdist.exe) will not affect your current web browser. Note
that you must restart your computer after installing Diskeeper Administrator if these components are
installed.
8.
If the MMC is not installed on your computer, the MMC Setup program is started automatically. After the
MMC files are installed, the Diskeeper Administrator Setup program resumes.
9.
After the Diskeeper Administrator files have been copied to your system, you may be presented with the
opportunity to register Diskeeper Administrator online.
10. You can immediately start Diskeeper Administrator by clicking Finish.
11. To run Diskeeper Administrator, click the Windows Start button, select Programs, and then Diskeeper
Administrator.
After the Installation
Registering Diskeeper Administrator
After the installation is complete, you may be given the option to register your Diskeeper Administrator
purchase online. Be sure to register your purchase to receive the free 90 days of telephone support included
with Diskeeper Administrator.
Check for Product Update
The first time you run Diskeeper Administrator, it automatically checks to see if a more recent version of
Diskeeper Administrator is available. If so, you are given the option to download and install the newer version.
When the download screen is displayed, click Run this program from its current location to begin installing
the update. Or, click Save this program to disk to save the Diskeeper Administrator update installation
package on your computer for later installation. (To install an update stored on your computer in this manner,
simply double-click the file you download and follow the instructions displayed.)
You can check for Diskeeper Administrator updates any time you want. Select the Configure Diskeeper
Administrator option under the Configure task group in the Quick Launch task pane and choose Diskeeper
6
Installation
Administrator Properties
. From the Properties Console, select the Diskeeper Administrator Updates
option on the left to see if a newer version of Diskeeper is available.
About Windows Service Packs
There is typically no need to upgrade Diskeeper Administrator each time you install a new Windows Service
Pack upgrade.
Important Note: Windows XP Service Pack 2 (SP2) establishes default security settings that can prevent
Diskeeper Administrator from communicating with Diskeeper computers throughout your network. Be sure to
visit www.diskeeper.com/sp2 for the latest information about configuring your Windows XP SP2 computers to
run Diskeeper Administrator and Diskeeper.
About the Diskeeper Administrator Service
Diskeeper Administrator creates a Windows service. The service allows the Administrator Data Controller to
run in the background while other applications are running. As long as your operating system is up and
running, Diskeeper Administrator can do its job, whether you are logged on or not.
After installation, the Diskeeper Administrator service starts automatically each time your computer is restarted.
This service runs all the time, whether or not any Diskeeper Administrator actions are occurring. This service
consumes negligible system resources, and in most cases will never need to be disabled.
The Windows Application Event Log
Diskeeper Administrator messages are placed in the Windows Application Event Log. By default, this log is
512 kilobytes in size (except on Windows Server 2003), and is set to overwrite events older than 7 days.
Diskeeper Administrator may quickly fill the log file if these default settings are used. To prevent this, perform
the following steps to change the size and overwriting characteristics of the Application Event Log:
1.
2.
3.
4.
Right-click My Computer on your desktop and select Manage.
When the Computer Management Console is displayed, select System Tools, and then Event Viewer.
Expand the Event Viewer by double-clicking it and select Application.
Next, click the Action menu and select Properties.
a) Set the Maximum log size to 2048 KB.
b) Enable the Overwrite events as needed option.
c) Click OK.
Repairing Windows Systems
Performing an emergency repair, upgrade or reinstallation of a Windows system can possibly change or disable
certain system information or services, which may make it necessary to reinstall Diskeeper Administrator after
repairing your Windows system.
Uninstalling Diskeeper Administrator
To uninstall Diskeeper Administrator, you must be logged into an account that is a member of the
Administrators group.
Note that the controls may have slightly different names, depending on the version of Windows.
Follow these steps to completely remove and uninstall Diskeeper Administrator from your computer:
Installation
7
1.
From the Control Panel, double-click Add/Remove Programs.
2.
Highlight the Diskeeper Administrator entry.
3.
Click Remove. This removes the Diskeeper Administrator program files from your computer. In most
cases, the Diskeeper Administrator installation directories will not be removed.
4.
Manually delete the Diskeeper Administrator installation directories if they exist.
Note: If the MMC has been installed on your computer, it will not be removed when Diskeeper Administrator
is uninstalled.
Also Note: Any data or installation files stored by the Administrator Data Controller are not removed when you
uninstall Diskeeper Administrator (in the event you are planning to reinstall Diskeeper Administrator).
Manually delete these files if they are no longer needed.

Chapter 3
Diskeeper Administrator Operation
This chapter describes the features available with Diskeeper Administrator, and what you can do with them.
Overview
These are the main Diskeeper Administrator features:
ƒ
Diskeeper Deployment—Install or uninstall Diskeeper Professional, Pro Premier , Server or
EnterpriseServer on selected computers throughout your network.
ƒ
Logical Grouping Control—Supports Active Directory groups, or you can create custom logical groups
of systems on which to manage Diskeeper operations.
ƒ
Policy-Based Centralized Management—Set and view Diskeeper defragmentation properties that control
how and when Diskeeper runs on selected computers on your network.
ƒ
Reports—Establish and view several Diskeeper reports showing information about selected computers on
your network.
ƒ
Alerts—Get e-mail notification of critical issues regarding the condition of the disk volumes all through
your network.
ƒ
Single Remote Computer Control—Connect directly to a remote system and have full control of
Diskeeper on that system.
ƒ
Cross-Platform Support—Diskeeper Administrator runs on a variety of Windows operating system
platforms, from Windows 2000 through Windows Server 2003.
Using the Diskeeper Administrator Console
Navigation in Diskeeper Administrator is done through the Diskeeper Administrator console. This console
provides a convenient central location to start all Diskeeper Administrator tasks and view reports.
Some Diskeeper Administrator tasks are performed in separate “Wizard” windows. These wizards guide you
through the steps necessary to perform that particular task. The layout of the wizards is similar to the main
Diskeeper Administrator console, and like the main console, the information and options displayed differs
depending on the task.
The Diskeeper Administrator console and various wizards were designed to guide you through all of the
available tasks quickly and easily. If any information or variables are required for a task, Diskeeper
Administrator takes you to the appropriate page and prompts you for the necessary input.
Common operations, such as scheduling a task, are presented in a consistent manner—scheduling a report scan
is done the same way as scheduling a Diskeeper deployment operation. Because of this, you will see similar
screens as you use the different the Diskeeper Administrator modules.

they will not be displayed.
Other Navigational Tips
You will notice Diskeeper Administrator uses several methods for getting your input or displaying information
that are consistent from one task to another. For example, selecting computers for a Diskeeper deployment task
is done in the same manner as selecting computers from which to generate reports. Or, filtering the data within
the different Diskeeper Administrator reports is done in the same way for each report type. This section briefly
describes some tips for using this consistency to your advantage.
Selecting Computers
Many Diskeeper Administrator tasks—such as creating reports or deploying Diskeeper—include a page for you
to select computers on which you want to perform the task. You can choose between two different views of
your network hierarchy: a tree view or a detail view.
Here is an example of the tree view:
12
Diskeeper Administrator Operation
Navigating the tree view is done in a manner very similar to other Windows-based applications like Windows
Explorer.
Click the plus sign
in the tree to expand a branch, or click the minus sign
to collapse the branch.
Click the View drop-down list to include custom groups, domains, Active Directory Organizational Units, or
computers grouped by IP address range:

Click the Tree/Detail view option
to switch between the tree view and the detail view:

13
Tree/Detail
view option
Here is an example of the Detail view:
Navigation
Buttons
Use the navigation buttons to move back, forward, and up through your network hierarchy to the desired
computers.
In either view, you select a computer by clicking on it. To select more than one computer, hold the <Ctrl> key
while clicking on the computers you want to select.
After selecting the desired computers or groups, use the Actions and Properties buttons (when displayed) to
perform a wide variety of tasks on the selected computers.
If you choose to display computers by IP address range, a page is displayed allowing you to provide the starting
and ending IP addresses for the range you want to display. See the following section for more information
about specifying an IP address range.
14
Diskeeper Administrator Operation
Specifying an IP Address Range
When you select Add IP Addresses from the Action option at the bottom of either the Tree or Detail computer
views, you can view a specific group of computers by entering an Internet Protocol (IP) address range. If you
enter an address in only the IP Address Start field, only the computer with that IP address is included. If you
specify an end address, all computers between the start and end addresses are included.
If the IP range covers multiple domains, you must enter the trusted domain name in the Domain field. When
one domain “trusts” another, the user name and password defined in the “trusted” domain can be used for
authentication and authorization in the “trusting” domain(s).
Additionally, if you want to indicate a mask used to determine the subnet an IP address belongs to, you can do
so on this page.
Follow these steps to enter an IP address range:
1.
In the Domain field, enter the name of the domain containing the machine(s) with the IP address or IP
address range you want to enter.
2.
You can include a single computer by entering an address in the IP Address Start field only.
3.
If you select the option to Specify End IP Address and enter an address, all computers with IP addresses
falling within the range are included.
4.
If you want to indicate the mask used to determine what subnet an IP address belongs to, select the Specify
IP Mask option and enter the mask in the accompanying field.
Filtering Reports
Grids in the various Diskeeper Administrator displays feature “Quick Filtering.” Quick Filtering allows you to
quickly and easily display only the information you want to see in the grid. Click the down arrow at the top of
any column and choose filtering options to determine what displays in the entire grid.
When you select an item, only that item appears in the grid. When you select “(none)” no filtering is applied
and all items appear in the grid.
When you select “(custom)” the Custom Row Filter screen appears so you can build a custom filter statement to
determine the information that appears in the grid.

First Things First
Before using Diskeeper Administrator for the first time, there are several steps you should take.
Configuring the Database
Diskeeper Administrator relies on a database of Diskeeper-related information gathered from remote computers
across your network. Before using Diskeeper Administrator for the first time, you must configure the database.
You can also change the database configuration later with the Diskeeper Administrator Database
Configuration Wizard option available from the Configure task in the Quick Launch pane or Diskeeper
Administrator menu bar.
There are several steps involved in configuring the Diskeeper Administrator database. The entire process is
explained on-screen as you go through the configuration process.
in the Diskeeper Administrator Task Overview under Getting Started in the
Click Configure Database
Quick Launch task pane to open the Configure Database Wizard, which guides you through the configuration
process.
Here is a summary of the steps:
Specifying whether to use Microsoft SQL Server or MSDE
As the first step of configuring the Diskeeper Administrator database, you must specify whether to use
Microsoft SQL Server 2005, Microsoft SQL Server 2000 or the Microsoft SQL Server Desktop Engine
(MSDE) for the Diskeeper Administrator database.
The MSDE provides local data storage and is based on the data engine used in Microsoft SQL Server 2000.
It is provided on the Diskeeper Administrator CD-ROM, and is also available free of charge from the
Diskeeper Corporation web site.
Specifying the database server location
If you opt to use an existing database, the next step in the database configuration task is to specify which
computer you want to use as the database server for Diskeeper Administrator. The Database Servers:
drop-down list shows you the database servers detected on your network by Diskeeper Administrator.
Also as part of this step, you have the option of using your Windows login authentication to access the
Diskeeper Administrator database, or you can enter your SQL Server authentication login name and
password. Note that if the SQL database is not in the same domain as the instance of Diskeeper
Administrator you are running, you must use the SQL Server authentication method.
16
Diskeeper Administrator Operation
Specifying whether to use a new or existing database
This step allows you to specify whether to use a new or an existing database. You can also configure more
than one database as long as you give each database a unique name.
Specifying the database information
During this step you specify the directory folder where you want the Diskeeper Administrator database to
reside. You will also specify the maximum size for the database and optionally specify a name for the
database.
Note that you cannot create a directory on a remote server from this task. We recommend you create a
C:\Diskeeper Administrator directory folder on the remote server for the Diskeeper Administrator database.
Update Legacy Database
This step is only displayed in cases where you have chosen to use an existing Diskeeper Administrator
database from an earlier version if Diskeeper Administrator. This step will update the older database to be
compatible with Diskeeper Administrator 2007.
Summary
The final screen displayed in the Database Configuration Wizard confirms the successful configuration of
your Diskeeper Administrator database.
Setting Up Administrative Permissions
In order to gather the Diskeeper data from remote machines, Diskeeper Administrator must use login
credentials for an account that is a member of the Administrators group on the domain or workgroup being
polled. (This account information is also used by the Diskeeper Deployment feature described on page 17.)
Diskeeper Administrator allows you to use different login information for each domain or workgroup on which
you want to perform remote Diskeeper installations.
If you have not already specified login credentials, you will be prompted to do so the first time you initiate a
Diskeeper Administrator task requiring it.
You can change previously-entered account information at any time by following these steps:
1.
in the toolbar to display the Configure task group, select Diskeeper
Click Configure
Administrator Properties, then select Administrative Permissions from the task pane on the left.
2.
Highlight the domain(s) or workgroup(s) for which you want to specify login credentials.
3.
In the Type column, click the drop-down menu and select either Domain, Workgroup, or Local Admin,
depending on the type of account you are using to access the selected domain(s) or workgroup(s).
4.
Click the User Name field and enter the user name for an account that is a member of the Administrators
group on the selected domain or workgroup.
5.
Click the Password field and enter the password for the account entered in the previous step.
6.
If you are using a Domain account (as opposed to a Workgroup or Local Admin account), you can
optionally click the button in the Verify Account column to check the validity of the user name and
password you have entered.
7.
Click OK. When you click OK, the login credentials are verified on each domain or workgroup. A
message is displayed if any of the verification processes fail.

Ports Used by Diskeeper Administrator
In order to deploy Diskeeper and remotely control Diskeeper computers with Diskeeper Administrator, the
computers running Diskeeper must be configured to allow Diskeeper Administrator to communicate via these
ports:
ƒ
Diskeeper Administrator PushInstall port: 31029 — Diskeeper Administrator uses this port to deploy
Diskeeper to remote computers.
ƒ
Diskeeper Administrator console port: 31036 — Diskeeper Administrator remote control console receives
data from remote Diskeeper computers via this port.
ƒ
Spare Diskeeper Administrator console ports: 31056, 31076, 31096, 31116, 31136, 31156, 31176, 31196,
and 31216 — Diskeeper Administrator will use these ports if the default ports are unavailable.
ƒ
Diskeeper Administrator SQL port: 1434 — Diskeeper Administrator uses this port if the SQL database is
located on a remote computer.
Getting Started Display
After you have configured the Diskeeper Administrator database, the Getting Started task overview is
displayed. You can also display this page at any time by clicking Getting Started

Diskeeper Administrator configuration settings need no additional action.
18
Diskeeper Administrator Operation
ƒ
Use the Add License Files task to add Diskeeper licenses to the Diskeeper Administrator database for use
with Diskeeper installations throughout your network. A license is required for each instance of Diskeeper
on your network unless you install Diskeeper in Try and Buy mode—a fully functional 30-day trial.
ƒ
Use the Deploy Policies task to deploy defragmentation policies to the computers or groups you select.
Defragmentation policies are used to centrally manage how Diskeeper defragments your computers. You
can deploy the policies immediately, or at a later scheduled time.
ƒ
Use the Install Diskeeper task to install Diskeeper on the computers you choose. You can easily install
Diskeeper on one or more computers via central management with Diskeeper Administrator.
ƒ
Use the Create Policies task to establish and save different defragmentation policies for your computers or
groups. After the policies are created, you can then deploy them via central management to your Diskeeper
computers.
ƒ
Use the Create Reports task to launch the New Report Wizard and create a report. Diskeeper
Administrator Reports show useful information about the computers on your network, the versions of
Diskeeper installed on them, and a variety of other data related to the performance and reliability of your
computers.
ƒ
Use the Scan Computers task to scan your network and gather data from your remote Diskeeper
computers for use in the Diskeeper Administrator database. In order to have meaningful data, you can run a
one-time scan now or at a later time, or schedule recurring scans. After the initial scan, the database is
updated each time a Diskeeper-related task or job occurs.
ƒ
Use the Configure Alerts task to configure the thresholds at which Diskeeper Administrator Alerts are
triggered, and customize the list of recipients and the message they receive with the alert. Diskeeper
Administrator Alerts are sent when exception-based events occur that could affect the performance and
reliability of your computers.
ƒ
Use the Remote Control Diskeeper task to connect to an individual Diskeeper computer and control
Diskeeper on it as if you sitting in front of that computer. You can perform any Diskeeper operations on
that computer in the same manner as running Diskeeper on a local computer.
ƒ
Use the Configure Database task to launch the Diskeeper Administrator Database Configuration Wizard,
which will guide you through the necessary steps for the initial database configuration, or to make changes
to a previously-set configuration.
Scanning the Network
Diskeeper Administrator can scan your network to gather information about Diskeeper installations and
properties network-wide. By scanning the network, you will increase the accuracy ease of use of the other
Diskeeper Administrator tasks and features. You can choose to scan all your computers or a selected subset.
You can run a one-time scan, or schedule recurring scans.
Network scans are done via the Scan Computers Wizard. Follow these steps to use the Scan Computers Wizard
to scan one or any number of remote computers:
1.
Click Scan Computers in the Diskeeper Administrator Task Overview under Getting Started in the
Quick Launch task pane. (Or you can select the Scan Computers option in the Manage Diskeeper task,
then click Scan Computers.) This opens the Scan Computers Wizard in a separate window.
2.
In the introduction screen displayed, enter an optional name and description for the network scan job. The
details of the network scan will be displayed in the Diskeeper Administrator Job Queue, so having a
recognizable job name and description can be useful. When you have made your selections, click Next.
3.
The next screen displays a tree view of your network. (You can also switch to a Detail view as described
on page 11.) Select any combination of one or more computers, groups or domains you want to scan. After
selecting the computers to scan, click Next.

4.
Since scanning a large number of computers across the network can take some time and use network
bandwidth, you are next given the option to schedule the network scan task for a later time, or perform it
now. If you select to schedule the task for a later time, you are prompted to specify when the task is to
begin. You can also specify a time for the task to be stopped, even if it has not yet completed. This gives
you the flexibility to perform the task at a time when network bandwidth will not be impacted. Choose
when to scan the network, and click Next.
5.
Next, a summary is displayed, showing you the ongoing status of the network scan task. When the task is
complete, the summary is automatically saved in the Diskeeper Administrator Job Queue, along with other
similar reports. See page 37 for more information about the Job Queue. When you are done reviewing the
report, or when you are ready to perform another task, click Close.
Deploying Diskeeper
Use the Install and Uninstall Diskeeper task to install or uninstall Diskeeper Professional, Pro Premier,
Server, or EnterpriseServer on selected computers across your network. Be aware that you must have valid
Diskeeper licenses for the computers on which you intend to install Diskeeper. If you do not have licenses
available, Diskeeper will be installed in Try and Buy mode, with full functionality, but for a limited time only.
Note that you must have administrative permissions on all the selected computers to deploy Diskeeper. If
necessary, you will be prompted for the appropriate credentials.
Also note that the deployment operation requires the presence of a shared folder named ADMIN$ on each of
the target computers. The ADMIN$ share exists by default on Windows systems, unless it has been specifically
disabled or removed. See page 21 for information about determining if the ADMIN$ share exists on your
computer(s)
The Install and Uninstall Diskeeper task establishes a network connection with the selected machines, then
installs the selected Diskeeper edition to those computers. It relies on having the installable Diskeeper
package(s) available to be installed. The first time you deploy Diskeeper, you are prompted to browse for the
installation package you intend to use. You can use either a CD-ROM or downloaded installation package.
Once you choose the Setup.exe file, the installation package is copied to the Administrator database. If you
have previously selected an installation package, the Install Diskeeper 2007 wizard will display the edition and
version of the package, and allow you to browse for a different package if desired.
If you try to deploy a Diskeeper version that is not compatible with the target machine, a message explaining
the situation is displayed. Messages are also displayed to let you know the status of the installations.
Diskeeper installation is performed as a “job”, meaning the operation can be run immediately or scheduled to
run at a later time
Installing Diskeeper Across the Network
Follow these steps to use the Install Diskeeper 2007 Wizard to deploy Diskeeper to one or a few hundred
remote computers:

not “roll back” installations that have already been done.
About the ADMIN$ Share
The Diskeeper Administrator PushInstall feature relies on a shared folder named ADMIN$ on each of the target
computers. The ADMIN$ share exists by default on Windows systems, unless it has been specifically disabled.
Here are two ways to check for the presence of the ADMIN$ share on your computers:
ƒ
Open Windows Explorer and enter \\computer_name\ADMIN$ in the Address field (where
computer_name is the name of the computer you are checking). If the share does not exist, an error
message will be displayed. If it does exist, the contents of the WINNT folder will be shown.
ƒ
Right-click My Computer and select Manage to open the Windows Computer Management applet. Next,
select System Tools | Shared Folders | Shares. The right-hand pane will display a list of all shares for that
computer, including ADMIN$ if it exists.
If the ADMIN$ share has been removed or disabled on your computer, contact Diskeeper Corporation
Technical Support for assistance.
Updates and Upgrades
In addition to installing Diskeeper across your network, Diskeeper Administrator can check the Diskeeper
Corporation website for newer versions of Diskeeper, and when found, deploy the new versions to your
managed Diskeeper computers.
You can set Diskeeper Administrator to check daily for updates, and send an e-mail message or display a
desktop notification message to inform you when updates are available. You can also manually check for
updates any time you want.
There are several steps involved in updating or upgrading Diskeeper on your remote computers. The entire
process is explained on-screen as you go through the steps.
Update and Upgrade ⎯ What’s the Difference?
Before we start, it is important to understand the difference between updates and upgrades:
ƒ
Updates are no-cost incremental versions of Diskeeper, based on a common version number. For example,
version 2007 build 101 would be an update from 2007 build 100. No additional Diskeeper licenses
(beyond those currently in use) are required to deploy a Diskeeper update.
ƒ
Upgrades are changes from one major version number to the next (such as from version 10.0 to version
2007) You must own or purchase the appropriate Diskeeper license to upgrade a Diskeeper installation.
22
Diskeeper Administrator Operation
Update or Upgrade Step-By-Step
The steps for installing Diskeeper updates or upgrades are similar to deploying new Diskeeper installations.
You select the computers you want to update or upgrade, select several other parameters, then let Diskeeper
Administrator perform the task unattended.
task under
For both updates and upgrades, the starting point is the Install and Uninstall Diskeeper
Manage Diskeeper in the Quick Launch task pane or the Diskeeper Administrator menu bar. Select this task
and choose either the Update Diskeeper or the Upgrade Diskeeper options to launch a wizard-based series of
steps to guide you through the update or upgrade operation. After starting the appropriate wizard, follow the
steps displayed to either update or upgrade one or more Diskeeper installations. These steps are described in the
following sections.
Introduction
The Introduction page of the Update Diskeeper Wizard (or the Upgrade Diskeeper Wizard) provides spaces for
you to enter an optional name and description for the update or upgrade job. The details of the job will be
displayed in the Diskeeper Administrator Job Queue, so having a recognizable job name and description can be
useful. Make any desired changes, then click Next.
Select Computers
This page of the wizard displays a tree view of your network. (You can also switch to a Detail view as
described on page 11.) Select any combination of one or more computers, groups or domains on which you
want to install the update or upgrade. After selecting the computers on which to install Diskeeper, click Next.
Select Data Source
Before performing any update or upgrade task, Diskeeper Administrator must determine what versions of
Diskeeper are running on your remote managed computers. It can do this by either scanning the computers
now, or using previously-collected data stored in the Diskeeper Administrator database.
ƒ
Using “live” data ensures you are basing the update or upgrade on the most currently-available data.
However, a live data scan can take a considerable length of time on a large network. Also, a “live” data
scan will not take into account any remote managed computers that happen to be off-line at the time of the
data scan (such as notebook or laptop computers).
ƒ
Using data from the Diskeeper Administrator database is typically faster than using live data, but keep in
mind that it is only as current as the database. This database is updated whenever Diskeeper-related
changes occur on your remote managed computers. However, this data may not be current if the Diskeeper
Administrator database has been off-line for any length of time. When database data is used, any remote
managed computers (notebook or laptop computers) that happen to be off-line at the time of the data scan
will still be taken into account, since in most cases the database contains the most recent information about
the Diskeeper version on those computers.
After selecting the data source, click Next to continue.
Select Version
This page of the wizard shows the Diskeeper versions available, and allows you to specify the Diskeeper
version you want to deploy.
The Select Computers and Upgrades page of the Update and Upgrade module lists the computers you have
selected to update, and shows this information about each:
ƒ
Domain Name
ƒ
Computer Name
ƒ
Operating System
ƒ
Diskeeper Edition
Diskeeper Administrator Operation
ƒ
Current Version
ƒ
Selected Version
23
The Current Version column shows the Diskeeper version that is currently installed on the remote computer.
The Selected Version column contains a drop-down list of available Diskeeper versions. Use this drop-down
list to select the Diskeeper version you want to install on each selected computer.
If you are installing an upgrade, you will also see a table showing the type and number of Diskeeper licenses
you have available for deployment. For each type of license available, the table shows:
ƒ
Diskeeper Edition
ƒ
Combined License Count (includes volume and retail licenses)
ƒ
Number of Licenses Used
ƒ
Number of Licenses Available
Schedule Deployment
Since deploying Diskeeper updates or upgrades to a large number of computers across the network can take
some time and use network bandwidth, the Update and Upgrade module gives you the option to schedule the
deployment task for a later time, or perform it now.
If you select to schedule the task for a later time, use the controls provided to specify when the task is to begin.
You can also specify a time for the task to be stopped, even if it has not yet completed. This gives you the
flexibility to perform the update or upgrade deployment at a time when network bandwidth will not be
impacted. Make your selections and click Next.
Summary
Deployment to each individual computer is considered a “job”, so deployment to many computers could consist
of many jobs. The Update and Upgrade Summary shows the progress of the individual jobs that make up the
update or upgrade deployment task. As the jobs progress, you can see this information:
ƒ

When you are done reviewing the report, or when you are ready to perform another task, click Close. Keep in
mind that you can also see current and historical information about the update or upgrade tasks in the Diskeeper
Job Queues. See page 37 for more information about the Job Queues.
Managing Diskeeper Software Licensing
Your Diskeeper licenses are stored in the Diskeeper Administrator database, and assigned to remote computers
as needed. The Manage Diskeeper Software Licensing module gives you complete control over the distribution
and use of your Diskeeper licenses. You can easily see the number and types of licenses in use and how many
are available. You can also convert Try and Buy licenses into full licenses (or full licenses into trialware) or
purchase additional licenses online, all from a single location.
The Manage Diskeeper Software Licensing module can detect and manage existing Diskeeper licenses on your
network. It is also used by the PushInstall deployment option to manage the licenses of the Diskeeper
installations done by this instance of Diskeeper Administrator.

Diskeeper 2007 Administrator introduces the concept of policy-based centralized defragmentation
management. Defragmentation policies are a set of properties (or options) that specify how Diskeeper will
defragment the computers on which they are deployed. As an example, you use a defragmentation policy to
specify which volumes on your remote computers will have Automatic Defragmentation enabled, or the periods
of time you want Automatic Defragmentation turned off. Once a policy has been defined, it can be saved and
used again.
Diskeeper 2007 Administrator supports defragmentation policies for computers running Diskeeper 2007, as
well as legacy systems running Diskeeper 10 or Diskeeper 9. Note that the available property options vary,
depending on the version of Diskeeper the policy is intended to control.
Creating Defragmentation Policies
Diskeeper Administrator includes a default policy for computers running Diskeeper 2007, but you can also
create your own policies to meet your specific needs, including policies for older versions of Diskeeper.
Defragmentation policies are created from within the New Job Policy Wizard. To open the wizard, select the
option in the Diskeeper Administrator Task Overview under Getting Started in the
New Job Policy
Quick Launch task pane. Alternatively, click Manage Diskeeper in the Quick Launch task pane and select
Configure Defragmentation Policies.
This opens a listing of the existing defragmentation policies. Click Actions at the bottom of the screen, then
select New Job Policy. This launches the New Job Policy Wizard.
Tip: You can create new defragmentation policies from the Actions menu at other times when they are
needed, such as when deploying Diskeeper to remote computers.
It is important to note that Diskeeper 2007 contains a number of significant improvements over Diskeeper
versions 9 and 10. First and foremost, Diskeeper 2007 offers Automatic Defragmentation, which simplifies
Diskeeper operation (and administration) considerably. With Diskeeper 2007 there is no longer a need for
multiple and potentially confusing Primary, Secondary, and I-FAAST™ defragmentation schedules, different
defragmentation methods, or any need to be concerned with disk or CPU priorities.
When you launch the New Job Policy Wizard, you will see options to create policies for Diskeeper 2007 or for
Diskeeper versions 9 and 10. The options available differ, depending on the Diskeeper version they are
intended for, and the policy type selected. Select the version and policy type, specify a name for the policy, and
click Next to continue and select the specific policy options you need. Note that the policy options you choose
will only be applied to the volumes you select from the list at the top of the New Job Policy Wizard.
The following sections give an overview of the options available for both Diskeeper 2007 and Diskeeper 9 and
10 policies.

Diskeeper Administrator Operation
Diskeeper 2007 Defragmentation Policy Options
When you create a new Diskeeper 2007 defragmentation policy, the wizard guides you through these steps:
General Page
The General page of the New Job Policy Wizard allows you select the Diskeeper version for which you want to
create a new policy, and provides spaces to specify a name for the policy and any desired description.
Automatic Defragmentation
The Automatic Defragmentation page of the New Job Policy Wizard offers options to enable Automatic
Defragmentation on the volumes you’ve selected, and using the Automatic Defragmentation Timeline, you can
specify time periods when Automatic Defragmentation will be turned off on those volumes. Keep in mind that
performance will be maintained at peak levels when Automatic Defragmentation is left enabled at all times.
I-FAAST
I-FAAST (Intelligent File Access Acceleration Sequencing Technology), available on selected editions of
Diskeeper, accelerates performance by intelligently sequencing files on the volume.
The I-FAAST page of the New Job Policy Wizard provides the option to enable I-FAAST on the selected
volumes. You can select from these options:
Allow Diskeeper to enable or disable I-FAAST when beneficial — When this option is enabled, I-FAAST
will only be enabled on volumes that will benefit from I-FAAST acceleration. While most volumes will show a
noticeable performance improvement when I-FAAST is enabled, there are cases where the performance gain is
not significant enough to warrant the negligible system resources needed to support I-FAAST.
Always enable I-FAAST — Select this option to enable I-FAAST on the selected volumes, even if there will
be little or no potential performance gain.
Always disable I-FAAST — Select this option to disable I-FAAST on the selected volumes, even if there will
be beneficial potential performance gain.
Note that I-FAAST is only available on volumes on which Automatic Defragmentation is also enabled.
Summary
The Summary page of the New Job Policy Wizard shows information about the new policy you have created,
including the policy name, the Diskeeper version it applies to, the policy type, and any description you included
when you named the policy.
Diskeeper 9 and Diskeeper 10 Job Policy Options
Since Diskeeper version 9 and 10 differ significantly from Diskeeper 2007, the job policy options available are
also quite different. Of particular note are the different policy types. When creating defragmentation policies for
Diskeeper 9 and 10, you can create separate policies for Primary Defragmentation, Secondary Defragmentation,
I-FAAST Defragmentation, and Manual Defragmentation.
The New Job Policy Wizard displays slightly different steps as appropriate, depending on the type of job policy
you are creating,. The steps are described in the following sections:
General Page
Similar to creating a Diskeeper 2007 defragmentation policy, the General page of the New Job Policy Wizard
allows you select the Diskeeper version for which you want to create a new policy, and provides spaces to
specify a name for the policy and any desired description.
Job Schedule
The Job Schedule page is displayed when creating a new defragmentation policy for Primary, Secondary, or IFAAST defragmentation jobs. It offers options to enable the respective defragmentation job type on the
volumes you’ve selected. Use the other options available on the page to specify times when that type of
Diskeeper Administrator Operation
27
defragmentation job will run (or will not be allowed to run, depending on your choices). Job schedules are
applied on a per volume basis. In other words, you can apply different schedules to different volumes. If you
have used Diskeeper 9 or 10 before, the scheduling options will be familiar. If necessary, refer to the Diskeeper
9 or Diskeeper 10 Help or User’s Manual for full descriptions of the scheduling options available.
Defragmentation Methods
Available for Primary, Secondary, and Manual defragmentation jobs, the Defragmentation Methods page
allows you to specify the defragmentation method Diskeeper will use when all jobs of this type are run. Unlike
job schedules, which are applied on a per-volume basis, defragmentation methods are applied on a per-job type
basis. For example, when you select a defragmentation method for Primary Defragmentation jobs, that
defragmentation method will be applied to all Primary Defragmentation jobs. These defragmentation methods
are available:
ƒ
Quick Defragmentation — This method provides the fastest defragmentation. It reduces the
defragmentation time by placing the emphasis on defragmenting the fragmented files, rather than free
space consolidation, since this returns the greatest system performance gain. This defragmentation method
will complete faster and use fewer resources, but note that the free space consolidation will not be as
thorough as the other methods.
ƒ
Recommended Defragmentation — This is the default, proven and balanced mix of file defragmentation
and free space consolidation. It is designed to gain the best disk performance without using excessive
system resources.
ƒ
Comprehensive Defragmentation — This defragmentation method performs additional free space
consolidation. This method performs a normal Diskeeper defragmentation, but then additionally performs
extra processing to further improve free space consolidation. It is important to note this method requires
additional processing and time, and free space consolidation improvement will be gradual as the option is
used over time. Since the Comprehensive Defragmentation method is best suited for scheduled
defragmentation jobs, it is not available for Manual Defragmentation Jobs.
In addition to these options, you can specify how Diskeeper handles large files. When the Efficiently
defragment large files option is enabled, Diskeeper defragments large files only to the point where access time
is improved and further defragmentation will not return a significant improvement. This can save considerable
system resources and can significantly reduce the time to run a job.
Disk and CPU Priorities
You can control the amount of disk input/output (I/O) and CPU resources used by Diskeeper for Primary,
Secondary, and Manual defragmentation jobs. For each of these job types, the New Job Properties Wizard
allows you to control the disk and CPU priority.
Running at the lowest CPU priority minimizes the system performance impact when Diskeeper is
defragmenting a volume. However, defragmentation jobs running at the lowest priority can take substantially
longer to complete than those running at higher priorities, since Diskeeper “backs off” for any process running
at a higher priority (even screen savers). For this reason, you may have occasions where you want to run
Diskeeper at a higher CPU priority. Keep in mind, though, that your system performance may be impaired
when Diskeeper is run at higher priorities.
In addition to the different levels of CPU priorities to choose from, you are also given the option to enable I/O
Smart™ on the selected volumes. This option takes the concept of run priorities one step farther by “throttling”
(suspending) the defragmentation process whenever disk I/O activity is detected on a disk while it is being
defragmented. This ensures the defragmentation process will be transparent to users, no matter how active the
disk.
Similar to the defragmentation method options, the Disk and CPU priority settings are applied on a per per-job
type basis. For example, when you specify disk and CPU priority options for Secondary Defragmentation jobs,
those settings will be applied to all Secondary Defragmentation jobs.
Keep in mind that even with the disk and CPU priority options, Diskeeper versions 9 and 10 do not provide the
performance gain and “invisible” operation offered by Diskeeper 2007 with Automatic Defragmentation.

Summary
The Summary page of the New Job Policy Wizard shows information about the new policy you have created,
including the policy name, the Diskeeper version it applies to, the policy type, and any description you included
when you named the policy.
Deploying Defragmentation Policies
After you have created defragmentation policies, you can deploy them to the computers of your choice. (Of
course, the remote computers must have Diskeeper installed on them.)
Defragmentation policies are deployed from within the Job Policy Deployment Wizard. Follow these steps to
open the wizard and deploy a defragmentation policy to one or a few hundred remote computers:
1.
Click Deploy Job Policy in the Diskeeper Administrator Task Overview under Getting Started in the
Quick Launch task pane. This opens the Job Policy Deployment Wizard in a separate window.
Alternatively, click Manage Diskeeper in the Quick Launch task pane and select Configure
Defragmentation Policies. This opens a listing of the existing defragmentation policies. Click Actions at
the bottom of the screen, then select Deploy Job Policy.
2.
In the introduction screen displayed, enter an optional name and description for the deployment job. The
details of the policy deployment job will be displayed in the Diskeeper Administrator Job Queue, so having
a recognizable job name and description can be useful. When you have made your selections, click Next.
3.
The next screen displays a tree view of your network. (You can also switch to a Detail view as described
on page 11.) Select any combination of one or more computers, groups or domains on which you want to
deploy the selected defragmentation policies. After selecting the computers on which to deploy the policy,
click Next.
4.
Next, you are given the opportunity to select the defragmentation policy you want to deploy. Select from
any of the policies displayed. You can modify an existing defragmentation policy by clicking Properties,
or click Actions and select the option to create a new policy. After selecting the defragmentation policy,
click Next.
5.
Since deploying defragmentation policies to a large number of computers across the network can take some
time and use network bandwidth, you are next given the option to schedule the policy deployment task for
a later time, or perform it now. If you select to schedule the task for a later time, you are prompted to
specify when the task is to begin. You can also specify a time for the task to be stopped, even if it has not
yet completed. This gives you the flexibility to perform the task at a time when network bandwidth will not
be impacted. Choose when to perform the policy deployment job, and click Next.
6.
Next, a summary is displayed, showing you the ongoing status of the defragmentation policy deployment
task. When the task is complete, the summary is automatically saved in the Diskeeper Administrator Job
Queue, along with other similar reports. See page 37 for more information about the Job Queue. When you
are done reviewing the report, or when you are ready to perform another task, click Close.
Editing Existing Defragmentation Policies
Defragmentation policies are edited from within the Defragmentation Policy Properties pages. To open the
properties page for an existing defragmentation policy, click Manage Diskeeper in the Quick Launch task pane
and select Configure Defragmentation Policies. This opens a listing of the existing defragmentation policies.
Select the policy you want to edit and click Properties at the bottom of the page. This launches the
Defragmentation Policy Properties pages for the selected policy.
Tip: You can simply double-click a defragmentation policy in the Configure Defragmentation Policies
listing to quickly open the Defragmentation Policy Properties pages for that policy.
Diskeeper Administrator Operation
29
After opening the Defragmentation Policy Properties pages, choose from the steps listed on the left of the page
and make any changes desired, similar to creating a new defragmentation policy. When you have made your
changes, click OK to save the changes and return to the Configure Defragmentation Policies listing, or click
Apply to save the changes without closing the Defragmentation Policy Properties pages for that policy.
Also note that when editing an existing defragmentation policy, you can click the Associated Computers step
shown on the left side of the page to see a listing of the computers to which the policy has been applied.
Diskeeper Reports
Diskeeper Administrator provides a variety of useful reports regarding the computers on your network. These
reports can be for any number of machines, based on the computers you have selected.
All reports are shown in a secondary window, independent of the main Diskeeper Administrator console.
Reports can be saved and printed. Following the “centralized management” concept, Diskeeper Administrator
allows you to perform a number of tasks directly from a report. After a report has been generated, you can
select one or more computers in the report, then use the Actions button at the bottom of the report to install or
uninstall Diskeeper, update or upgrade Diskeeper, deploy defragmentation policies, or remotely-control a
Diskeeper computer.
Details about the Reports
Diskeeper Administrator gathers information each time Diskeeper-related changes occur on any remote
Diskeeper computers being managed by that instance of Diskeeper Administrator. This information is stored in
the Diskeeper Administrator database.
You can generate reports based on real-time data or data stored in the Diskeeper Administrator database. Realtime data offers the most current view of your managed Diskeeper computers, since Diskeeper Administrator
polls each selected computer when this option is selected. However, this polling process can take a considerable
length of time on a large network, and a certain amount of network traffic occurs. Database data gathering is
typically much faster, but it may not be completely current, especially if the Diskeeper Administrator database
has been off-line for any length of time.
Diskeeper Administrator reports are comprised of specific sets of data, presented in a tabbed format. Each
report can contain any or all of these individual data sets (also known as report sections):
Diskeeper Computers – shows information about the Diskeeper status on the computers managed by this
instance of Diskeeper Administrator.
Fragmentation and Performance – shows factors that directly affect the performance and reliability of your
disk volumes, such as MFT fragmentation, paging file fragmentation and the level of free space. This data set is
a useful way to show Diskeeper is maintaining the good health of the system.
Computers and Policies – shows information about Diskeeper versions installed and defragmentation policies
in place on the computers managed by this instance of Diskeeper Administrator.
Alert History – shows information about any Diskeeper alerts that have been generated on the computers
managed by this instance of Diskeeper Administrator.
Also note that you can save and print reports you create. Click Actions at the bottom of the report window to
see the available report options.

ƒ Alert Time
When the Alert History data set is selected, you are given the option to include all Diskeeper Administrator
alerts in the report, or specify a range of time for you want to see any alerts.
The Alert History data set is similar to the standard Diskeeper Administrator alerts (as described on page 33),
but since you can specify a starting and ending time period to examine, it is useful for seeing a compilation of
Diskeeper Alerts covering a specific time period.
Creating a Report
The Create Report Wizard guides you thorough the steps necessary to create a report. Here is an overview of
those steps:
To open the Create Report Wizard, select the Create Reports option in the Diskeeper Administrator Task
Overview under Getting Started in the Quick Launch task pane. Alternatively, click Reports and Alerts in
the Quick Launch task pane and click Create Report at the bottom of the screen. This launches the Create
Report Wizard.
Naming the Report
The first page of the Create Report Wizard offers allows you to specify and name and description for the report
you are creating. Since reports can be saved and recalled at a later time, a meaningful report name and
description can be useful. Enter a name and description as desired, then click Next to continue.
Selecting the Data Sets
Use this page of the wizard to specify the data sets (or report sections) to be included in the report. You can
choose from these available data sets. (See page 29 for descriptions of these data sets):
ƒ
Diskeeper Computers
ƒ
Fragmentation and Performance
ƒ
Computers and Policies
ƒ
Alert History
When the Alert History data set is selected, you are given the option to include all Diskeeper Administrator
alerts in the report, or specify a range of time for you want to see any alerts.
After selecting the data sets to include in the report, click Next.
Selecting Computers and Groups
Use this page of the wizard to select the computers and/or groups to be included in the report. This page shows
a tree view of your network. (You can also switch to a Detail view as described on page 11.) Select any
combination of one or more computers, groups or domains you want included in the report. After making your
choices, click Next.
Specifying the Data Source
Use this page of the wizard to specify the source for the data used in the report. You can use data that is already
in the Diskeeper Administrator database, or create the report based on real-time data gathered immediately or at
a later time you specify.
Note that managed Diskeeper computers automatically send report and alert data to Diskeeper Administrator
after completion of a scheduled defragmentation job.
32
Diskeeper Administrator Operation
Real-time data offers the most current view of the managed Diskeeper computers on your network, but
gathering the data can take some time and incur network overhead.
Using data from the Administrator database is faster and less costly in network bandwidth, but it may not
reflect the most current Diskeeper information on your network. This is especially true if the Diskeeper
Administrator database has been off-line for any period of time.
Choose the data source you want to use for your report, then click Next to continue.
Specifying the Report Schedule
Since gathering report data from a large number of computers across the network can take some time and use
network bandwidth, this page of the Create Report Wizard gives you the option to schedule the report
collection task for a later time, or perform it now.
If you select to schedule the task for a later time, use the controls provided to specify when the task is to begin.
You can also specify a time for the task to be stopped, even if it has not yet completed. This gives you the
flexibility to gather the report data at a time when network bandwidth will not be impacted.
Choose the desired schedule, then click Next to continue.
Report Wizard Summary
Next, a summary is displayed, showing any schedule you specified for the reporting task. The Summary page
also allows you to specify whether to save the report as a template in the Reports Console for later use. You can
also choose to e-mail a copy of the report to the recipients of your choice.
When you are done making any of these optional choices, click Finish.
If you chose to generate the report immediately, the report is displayed in a separate window, with tabbed pages
for each data set you specified.
If the report task was scheduled to run at a later time, the Report Console is displayed, listing any saved report
templates.
Viewing Report Status
After a report has been created, you can optionally check the status of the report. Follow these steps:
1.
Click Diskeeper Job Queue in the Quick Launch task pane and select the report in question.
2.
Click Actions at the bottom of the console, and select View Status.
This shows information about the success of failure of the data-gathering operation on each selected computer
Filtering a Report
Regardless of the type of report, Diskeeper Administrator provides powerful filtering capabilities, allowing you
to view the data you need most.
As mentioned earlier in this manual, grids in the various Diskeeper Administrator reports feature “Quick
Filtering.” Quick Filtering allows you to quickly and easily display only the information you want to see in the
grid. You can click the down arrow at the top of any column and determine what displays in the entire grid.
Diskeeper Administrator Operation
33
When you select an item, only that item appears in the grid. When you select “(none)” no filtering is applied
and all items appear in the grid.
When you select “(custom)” the Custom Row Filter screen appears so you can build a custom filter statement to
determine the information that appears in the grid.
Saving a Report
When you are viewing a report, you can save it for future reference. Click Actions at the bottom of the report
and select Save as to save the report. You are given the option of specifying the location where the report file
will be saved. You can navigate to the disk volume and folder of your choice.
Printing a Report
Saved reports can be printed. Click Actions at the bottom of the report and select Print to print the report. A
standard Windows print dialog box is displayed where you can select which printer to send the report to, and
other printing options.
Launching Other Actions from a Report
In addition to viewing, printing, and saving a report, you can select one or more computers in a report, then
launch other actions to perform on them, directly from the report. Using the options available in the Actions
menu at the bottom of each report, you can install, uninstall, update, or upgrade Diskeeper on the selected
computers, deploy defragmentation policies, move computers or groups in the Custom Groups hierarchy, or
remotely control Diskeeper on a single computer.
For example, you can create a report using the “Diskeeper Computers” data set to show which computers do or
don’t have Diskeeper installed, select the computers on which you want to install Diskeeper, and immediately
begin the deployment, directly from the report. As you use the Diskeeper Administrator reporting capability,
you will likely find numerous ways where Diskeeper Administrator can save time and effort in your
management of Diskeeper across your network.
Diskeeper Alerts
Diskeeper Administrator can be set up to send you e-mail alerts informing you of situations that affect the
performance and reliability of the computers being controlled by Diskeeper Administrator.
Alerts are based on data received from managed Diskeeper installations throughout your network. Diskeeper
Administrator examines this data to determine whether an alert should be generated. This data is gathered as
Diskeeper-related events occur on managed Diskeeper computers throughout your network.
34
Diskeeper Administrator Operation
Alerts are logged and stored in the Administrator database as they are detected. Alerts are sent to you (or the
people you designate) as individual e-mail messages for each Alert. You control whether (and to whom) these
e-mail messages are sent.
Alerts are generated under these conditions:
ƒ
A Diskeeper defragmentation job does not complete on a volume for any reason
ƒ
If free space has reached a critical level on an individual machine. (The free space affects the Volume
Health index, which is described in detail shortly.) You can set the free space threshold at which these
Alerts are generated.
Diskeeper Corporation has done extensive research into the causes of disk performance and reliability
problems. This research has shown these factors play a significant role in regards to disk performance and
reliability:
ƒ
Overall fragmentation (described below)
ƒ
MFT fragmentation
ƒ
Paging file fragmentation
ƒ
Available free space
Diskeeper uses these factors to determine a disk reliability index each time it analyzes or defragments a disk
volume.
Disk reliability is rated into three categories—Healthy, Warning and Critical.
This table shows the Warning and Critical levels used in determining the reliability index.
Reliability Factor
Warning Level
Critical Level
Overall Fragmentation
> 10% fragmentation
> 50% fragmentation
MFT Fragmentation
> 250 fragments
>2000 fragments
Paging File Fragmentation
> 250 fragments
>1500 fragments
Free Space
< 15% free space
< 5% free space
The Overall fragmentation figure is calculated by dividing the time required to read the fragmented files on the
volume by the time required to read all the files on the volume, and multiplying the result by 100.
How to Receive Alerts
Diskeeper Administrator delivers alerts in two ways:
ƒ
An Alert Report displayed directly in the Diskeeper Administrator console
ƒ
An Alert Report e-mailed to you or the people you designate
You have control over which alerts are reported to you. For each type of e-mailed alert, your options are:
ƒ
All alerts
ƒ
Alerts occurring between the starting and ending dates you specify
In order to receive alerts by e-mail, you must specify at least one e-mail address. You will be prompted for this
information the first time you set up any type of Diskeeper Administrator task that requires an e-mail address.
Diskeeper Administrator Operation
35
Configuring Alerts
Alerts are based on post-defragmentation data received from remote Diskeeper 9.0 (or higher) installations
throughout your network. Diskeeper Administrator examines this data to determine whether an alert should be
generated. This data is sent to Diskeeper Administrator any time Diskeeper-related activity or changes occur on
your managed Diskeeper computers.
Alerts are logged and stored in the Administrator database as they are detected. Alerts are sent to you (or the
people you designate) as individual e-mail messages for each alert, and/or by a daily report, which is also sent
via e-mail. You control whether (and to whom) these e-mail messages are sent.
Follow these steps to configure alerts:
1.
in the Diskeeper Administrator Task Overview under Getting Started in
Click Configure Alerts
the Quick Launch task pane to open the Alerts Properties dialog.
2.
In the General page displayed, select the exception-based events that will trigger an alert. You can choose
to have alerts triggered by incomplete defragmentation due to engine failure, or when free space on a
volume reached a threshold you set, or both.
3.
Click Select Computers in the Properties task pane on the left side of the Alerts Properties dialog, then use
the tree view displayed to select the computers for which you want alerts to be generated. (You can also
switch to a Detail view as described on page 11.)
4.
Next, click Alert E-mail in the Properties task pane on the left side of the Alerts Properties dialog. On the
page displayed, select your choice of options to send a daily Alert Summary report via e-mail, and specify
the e-mail address(es) intended to receive the Alert Summary. You can also optionally edit the subject line
and body of the message.
5.
After selecting the settings you want, click OK to close the Alerts Properties dialog.
Setting Up Alert and Task Purge Options
Diskeeper Administrator stores Diskeeper alert data and details about Diskeeper Administrator tasks in the
Diskeeper Administrator database. Over time, this information should be purged to avoid consuming
unacceptable amounts of disk space. By default, Diskeeper Administrator keeps Alert data for 30 days, and task
data for 15 days, but you have control over how often this data is cleared out.
You can specify how long to save Diskeeper alerts and one-time tasks in the Diskeeper Administrator database.
Diskeeper Administrator will keep alerts and one-time tasks in the database for a maximum of 180 days. Note
that repeating tasks (such as scheduled report scans) are not purged.
Follow these steps to change the purge options:
1.
Click Configure in the Quick Launch task pane, then select Diskeeper Administrator Properties
2.
Click Purge Queue and Alert History in the Configure task pane on the left side of the display.
.
This page provides these options:
•
Clear Alerts
•
Clear Tasks
For each option, you can set the number of days (from 0 to 180) for Diskeeper Administrator to keep the
alerts or tasks in the database. You can also click the respective button to clear alerts or tasks immediately.
3.
When you have made any desired changes, click OK to close the dialog and return to the main Diskeeper
Administrator console.
36
Diskeeper Administrator Operation
Using Groups
Diskeeper Administrator allows you to create and use logical groups of computers on your network. These
groups can then be controlled and managed as a single unit. For example, you might create a group that consists
of all the computers in the Accounting Department, or all the workstations on the third floor. Then, when you
need to perform a Diskeeper Administrator task such as deploying Diskeeper or defragmentation policies to
multiple machines, you simply select the group of computers (as a single unit) instead of each computer in the
group.
In addition to custom groups you create, Diskeeper Administrator also supports any groups you have created
within Microsoft Active Directory. Here again, you can apply Diskeeper Administrator tasks to Active
Directory groups in the same manner as applying them to a single machine.
Creating Custom Groups
Custom groups are made up of one or more of the computers on your network. A group can include entire
domains or workgroups, and can also include other groups.
Click Manage Diskeeper in the Quick Launch task pane, then select Manage Diskeeper Computers and
Custom Groups
. This displays a tree view of your network.
Once the tree view is displayed, follow these steps to create a new custom group:
1.
Click My Groups in the tree view display.
2.
Click Actions in the bottom of the console, and select New Custom Group. Alternatively, right-click My
Groups and select New Custom Group. A dialog is displayed, allowing you to specify the name of the
new custom group.
3.
Edit the name of the new group displayed in the Computer View section of the page.
4.
Next, navigate the tree view to display the domains, workgroups or computers you want to include in the
new group. Drag and drop your choices into the new group displayed under My Groups. The new group
will now be available from the various Select Computer pages throughout Diskeeper Administrator.
Managing Custom Groups
To add computers to an existing group, open the tree view display and simply drag and drop the computers into
the custom group.
To remove a computer from a custom group, right-click on that computer in the group and select Remove
Selected Computers. You can also remove multiple computers in this manner – select the computers you want
to remove from the group, then right-click one of the selected computers and select Remove Selected
Computers.
You can also add, modify or delete custom groups using the options available from the Action button in any of
the tree view pages shown for Diskeeper Administrator tasks that allow you to select computers or groups.
Remote Control
You can use Diskeeper Administrator to remotely control Diskeeper 9.0, 10.0 and 2007 operations on
computers all over your network. (Of course, Diskeeper Professional, Pro Premier, Server, or EnterpriseServer
must be licensed and installed on the remote computers.) Without ever leaving your desk, you can perform any
Diskeeper task as if you were sitting at the remote machine.
To connect to and control a remote computer, follow these steps:
Diskeeper Administrator Operation
37
1.
Click Remote Control Diskeeper in the Diskeeper Administrator Task Overview under Getting Started
in the Quick Launch task pane.
2.
In the tree view displayed, select the computer on which you want to run Diskeeper, and then click Remote
Control. (If the computer you want to control remotely is not visible in the tree view, you can enter the
appropriate domain and computer name or IP address in the space provided at the bottom of the dialog.)
3.
Once the computer is connected, the Diskeeper console opens in a new window and the name of the
computer being controlled is shown at the top of the Diskeeper display.
Error messages will be displayed if Diskeeper fails to connect to the remote computer.
After connecting to Diskeeper on the remote computer, perform any Diskeeper operations on that computer in
the same manner as running Diskeeper on a local computer.
Editing Exclusion Lists on a Network
Diskeeper allows you to list files and directory folders that you do not want moved. This “exclusion list” is
checked by Diskeeper each time defragmentation is run. To edit exclusion lists on remote computers on your
network, you must have sufficient permissions to edit a file in the Diskeeper directory on the remote computer.
If you do not have sufficient permissions, an error message is displayed stating that access is denied to the
exclusion list. If you cannot edit an exclusion list that you think you have permission to use, there are two likely
possibilities:
ƒ
You logged on with a username that the target computer recognizes and a password that it does not
recognize. A common example is to log on to your computer as Administrator and then try to edit an
exclusion list on a computer that has its own Administrator account established with a different password.
ƒ
Your computer and the remote computer do not share the same network protocol.
For more information about Diskeeper Exclusion Lists, see page 42.
Diskeeper Job Queue
The Diskeeper Job Queue option provides a centralized location for information about any pending, running or
completed Diskeeper Administrator tasks (or jobs) you have performed. You can stop a current or pending job,
and view the status of a job to see detailed information about whether it completed successfully for all selected
computers.
Select Diskeeper Job Queue in the Quick Launch task pane to open a view of the job queue.
The Job Queue filter at the top of the Job Queue console offers these views:
ƒ
All Jobs
ƒ
Reporting Jobs
ƒ
Configure Setting Jobs
ƒ
Deployment Jobs
ƒ
Scan Machine(s) Jobs
Select any of these filtering options to see a listing of past, present and scheduled jobs of that category. The
typical listing shows the job name, the task type (such as Deployment tasks or Scan Machine(s) jobs), the job
type (one-time or scheduled, for example) and the last run time and date.
Double-click any of the jobs listed to see a detailed report about the status of the job. This is a useful way to see
the computers on which a specific job was or was not successful. You can see details about the domain, the
machine name, the status of the job, a description or explanation of the reported status, and the date and time
the status was recorded.

What’s New in Diskeeper 2007
The term Paradigm Shift is somewhat overused when describing technical breakthroughs, but Diskeeper 2007
does indeed represent a major shift in the way you will improve the performance and reliability of your
computers. For over a decade, Diskeeper has led the way in Windows system defragmentation technology, but
Diskeeper 2007 takes such a significant step forward that paradigm shift is truly the most appropriate term to
describe it.
Whether you’ve used Diskeeper before or not, you may already be familiar with some of its features, but
Diskeeper 2007 represents a major milestone in the progression of Diskeeper development. New users will find
Diskeeper to be easy to use, yet comprehensive in its capabilities. Experienced Diskeeper users will see major
changes, yet still recognize familiar features, presented in a new, more streamlined way. This list gives a
summary of what’s new in this version.
ƒ
Automatic Defragmentation
Diskeeper has made its reputation with the trademarked phrase “Set It and Forget It®,” meaning that once
Diskeeper is installed, you can simply forget about it. Defragmentation was taken care of automatically and
your computer was kept at peak performance all the time.
However, times have changed. Disk drives have grown huge. And, with the growth of disk drives has
come an explosion in the size and number of files stored on disk drives. With terabyte drives (a trillion
bytes) now easily available and smaller drives selling for very little money, you can store a LOT of stuff—
practically everything. And file sizes are continuing to increase as well. Documents with embedded
graphics, large presentations, scanned images, digital photos, MP3 music files and even whole TV shows
and movies are now residing on hard drives. The vast quantities of these and their inordinate size present
new challenges for computer performance and make defragmentation more critical than ever.
As disks have grown bigger and files have grown larger and more numerous, defragmentation is required
more and more often to maintain a computer’s performance. While it used to be sufficient to defragment
once a week, it eventually became necessary to defragment daily. Today, even daily defragmentation is not
enough. An hour’s production activity can seriously degrade performance.
But scheduling a defragmenter to run every hour is scary to performance-conscious System Administrators
and computer users. Even with features like I/O Smart and selectable run priorities, they are reluctant to
run a defragmenter in the middle of the workday.
The answer is our new InvisiTasking™ technology. InvisiTasking uses a proprietary technique developed
in our research lab to carefully monitor resource consumption on a Windows computer system and inject
Diskeeper processing into the unused portions—and only into the unused portions. InvisiTasking is so
good that it is all but impossible to even detect whether Diskeeper is running. That means Diskeeper can
run all the time. It never needs to back off or shut down to reduce overhead, since overhead is already
virtually non-existent! This means no more need for scheduling defragmentation. In fact, scheduling
defragmentation worsens performance by delaying the improvement that defragmentation brings.
Diskeeper with InvisiTasking means a computer performs at peak all the time, around the clock, not just
for a few minutes after each scheduled defragmentation run.
40
Overview of Diskeeper Features
The Dashboard tab in the Diskeeper display includes a real-time graph showing the idle resources on your
computer, and the small portion of those unused idle resources used by Diskeeper with InvisiTasking.
(Note that the graph also shows resources used when Diskeeper is run manually.) Now, you may be
skeptical at first and find it hard to believe InvisiTasking has virtually no impact on system overhead. For
this reason, you can specify times when Diskeeper is prevented from running at all. Eventually, we are sure
you’ll be convinced, and lock-out scheduling will be forgotten. The scheduling era is over, and the era of
truly automatic defragmentation has begun.
ƒ
I-FAAST 2.0
Introduced in Diskeeper 10, and refined in Diskeeper 2007, the second generation of Intelligent File
Access Acceleration Sequencing Technology (I-FAAST) goes beyond “normal” defragmentation to speed
up your file access and creation times. Traditionally, a defragmenter like Diskeeper could restore the
performance of a computer to like new condition. I-FAAST, however, can improve the computer’s
performance to better than new!
I-FAAST improves file access and creation by up to 80% (average 10%-20%). This is the first industry
implementation of “Disk Performance Calibration”, the modern evolution of the outdated and inconclusive
disk optimization strategies of the past.
When I-FAAST is enabled, Diskeeper runs specially-engineered benchmarks on your disk volumes to
learn their performance characteristics. Diskeeper then transparently monitors volumes for file access
frequency on an ongoing basis to determine which files are requested most often. Special analysis
techniques prevent Diskeeper from being “fooled” by files that have been recently accessed.
Using newly-developed technology, Diskeeper sequences the files to take best advantage of both the
logical characteristics and physical characteristics of the volume. The sequencing process is integrated with
background defragmentation, so it's virtually transparent to you.
The I-FAAST 2.0 engines have been refined to use InvisiTasking technology and to provide advanced
online directory consolidation and improved boot optimization. You can also now select specific files to be
included in the I-FAAST processing.
I-FAAST intelligence allows Diskeeper to adapt to changing situations—so if the demands on a given
system change, Diskeeper automatically adjusts its behavior accordingly.
The I-FAAST feature is included in Diskeeper EnterpriseServer, Diskeeper Server and Diskeeper Pro
Premier editions.
ƒ
TVE™ 2.0
Terabyte Volume Engine™ 2.0 has been enhanced to use the InvisiTasking technology, and to better
consolidate free space. The TVE is available in Diskeeper EnterpriseServer.
ƒ
Improved User Interface
The Diskeeper console has been enhanced to reduce the number of steps necessary to perform typical
tasks, and to improve the overall user experience. This includes a new, easy-to-use “timeline” control for
specifying the times when Automatic Defragmentation is turned on and off.
Diskeeper Features
The following list summarizes the most important Diskeeper features:
Automatic Operation—Diskeeper is designed to operate without your intervention. Simply install Diskeeper,
then sit back and let it take care of the details. Of course, you can also run Diskeeper manually. (But you
probably have better things to do with your time. That’s what Automatic Defragmentation with InvisiTasking is
for!)
Overview of Diskeeper Features
41
Diskeeper Family of Products—The Diskeeper family of products offers specialized automatic
defragmentation of Windows operating systems ranging from Windows 2000 through Windows Server 2003
Datacenter. See the tables in Appendix A for the complete Diskeeper lineup.
Descriptive Console Interface—The Diskeeper console provides an intuitive and informative defragmentation
experience. Common commands are grouped together in the Quick Launch pane, and a group of tabbed panes
show you a wide variety of information. Diskeeper shows you the condition of your disks, and provides
suggestions for improving or maintaining your disks.
Performance and Volume Health Analysis—Diskeeper collects and displays data regarding the performance
and overall health of your volumes in the Dashboard tab. This information allows you to be more proactive in
the management and maintenance of your computers.
I-FAAST — Intelligent File Access Acceleration Sequencing Technology (I-FAAST) improves file
access/creation by up to 80% (average 10%-20%) above and beyond the improvement provided by
defragmentation alone. This is the first industry implementation of “Disk Performance Calibration”, the modern
evolution of the outdated and inconclusive disk optimization strategies of the past.
Terabyte Volume Engine—A Diskeeper exclusive, the terabyte volume engine (TVE) is designed to
efficiently defragment extremely large (larger than 60 GB) volumes. This feature is available in selected
Diskeeper editions. The table in Appendix A shows the Diskeeper editions with TVE support.
Frag Shield™— One situation that can impair the performance and reliability of your computer is
fragmentation of the Master File Table (MFT) on NTFS volumes and your paging files. Since the operating
system relies heavily on the MFT and paging file, the effect of fragmentation is often much greater than when a
normal file is fragmented. Special measures must be taken to defragment these files, so it is better to prevent
their fragmentation in the first place. The Frag Shield feature helps you configure these critical system files
optimally, to help keep them contiguous from the start.
Boot-Time Defragmentation—Defragment files at boot-time that cannot be moved safely when Windows is
running.
Exclusion Lists—Diskeeper exclusion lists allow you to specify files and directories that will not be allowed to
be processed by Diskeeper.
Event Logging— Diskeeper records information about its activity in two ways. First, general information
about previously-run defragmentation job is shown in the Log tab within the Diskeeper console. Additional
information can also be stored in a log file. A wide variety of information can be saved for future reference.
Simultaneous Analysis or Defragmentation Operations—You can analyze and/or defragment more than one
disk volume at a time. Different Diskeeper editions support different numbers of simultaneous operations. See
Appendix A for more information.
Group Policy Support—Diskeeper can be configured network-wide with the Group Policy Editor provided
with Windows 2000 Server and Windows Server 2003.
Other Things to Know
ƒ
When running Diskeeper in Automatic mode, you can run other tasks while defragmentation is occurring.
ƒ
With the exception of boot-time operations, Diskeeper runs as a Windows Service and it optionally logs
useful defragmentation information into the Windows Application Event Log.
ƒ
Diskeeper can be uninstalled in the standard manner using the Add/Remove Programs applet in the
Windows Control Panel.
ƒ
Due to limits built into Windows 2000, Diskeeper cannot defragment files on NTFS volumes on Windows
2000 systems with a cluster size greater than 4KB (4096 bytes), except during Boot-Time
Defragmentation. This limitation has been removed in Windows XP and Windows Server 2003, where
Diskeeper can defragment NTFS volumes with cluster sizes of up to 64 kilobytes. Note the boot-time
defragmentation operations are not affected by this limit.
42
ƒ
Overview of Diskeeper Features
You must be logged into an account that is a member of the Administrators group to run Diskeeper.
Exclusion List
In some cases, you may have files or directory folders you do not want to defragment. For example, you may
not want to defragment temporary files that will soon be deleted. Any files or directories can be excluded from
Diskeeper processing by adding them to the exclusion list.
Additional information about the Diskeeper exclusion list is available in the Diskeeper Help or User’s Manual.
Frag Shield
One situation that can impair the performance and reliability of your computer is fragmentation of the Master
File Table (MFT) on NTFS volumes and your paging files. Since the operating system relies heavily on the
MFT and paging file, the effect of fragmentation is often much greater than when a normal file is fragmented.
Special measures must be taken to defragment these files, so it is better to prevent their fragmentation in the
first place. The Frag Shield feature helps you configure these critical system files optimally, to help keep them
contiguous from the start.
Additional information about Frag Shield is available in the Diskeeper Help or User’s Manual.
Event Logging
Diskeeper allows you to record information about its activity in a log file. You can alternately enable or disable
the logging of various events to the Diskeeper Event Log. The logging method varies, depending on the version
of Windows you are using.
Additional information about Diskeeper event logging is available in the Diskeeper Help or User’s Manual.
Theory of Diskeeper Operation
43
Chapter 5
Theory of Operation
This chapter describes the original Diskeeper design goals and how those goals were met.
Introduction
As described in the introduction of this manual, the term disk fragmentation means two things:
ƒ
a condition in which pieces of individual files on a disk are not contiguous, but rather are broken up and
scattered around the disk volume; and
ƒ
a condition in which the free space on a disk volume consists of little pieces of space here and there rather
than a few large free spaces.
The effects of excessive fragmentation are twofold as well:
ƒ
file access takes longer because a file must be collected in pieces here and there, requiring several disk
accesses instead of just one; and
ƒ
file creation takes longer because space for the file must be allocated in little pieces here and there instead
of just one contiguous allocation.
Before the introduction of Diskeeper, there was no method for completely correcting the problems of file and
free space fragmentation on Windows NT (and later) computers or in a Windows network.
Design Goals
In designing Diskeeper for Windows, the following goals were established:
ƒ
The product must be completely safe to use.
ƒ
It must improve Windows system performance. It is not designed to make the disk look “pretty”—it is
designed to improve disk performance and, as a result, overall system performance.
ƒ
It should process live disks without interfering with user access to files.
ƒ
It should run without operator intervention.
ƒ
It must defragment all possible files and consolidate free space into the smallest possible number of large
spaces.
Diskeeper defragments files and free space on a disk, allowing access to the files on the disk at any time while
Diskeeper is running.
Safety
Diskeeper is designed with safety as the highest priority.
To ensure the safe movement of files, Diskeeper uses mechanisms built into the operating system that were
developed and implemented by Diskeeper Corporation (then known as Executive Software), and fully
incorporated into Windows 2000, Windows XP, Windows Server 2003, and Windows Vista™ by Microsoft.
By using these built-in mechanisms, Diskeeper maintains cache coherency, file security and permissions
information, and file content integrity no matter how fragmented the files on the disk are.
44
Theory of Diskeeper Operation
The foremost design goal for Diskeeper is to make sure that no data is ever lost. To accomplish this goal
Diskeeper uses the following criteria for accessing files:
ƒ
the contents of data files are never modified under any circumstances
ƒ
only one file is processed at a time, not the whole disk
ƒ
no information is stored on any other device or in a “scratch space”
ƒ
Diskeeper accesses a file in such a way that no user access can conflict with Diskeeper during the critical
portion of the relocation process
ƒ
file relocation is aborted if any error is encountered, leaving the file in its original state
Diskeeper was designed to err on the side of caution. In other words, it only moves a file on the volume when it
is absolutely certain that no data will be lost, including file attributes. The only change to file attribute-type
information is the physical location of the file on the volume. None of the file dates are changed and no other
fields in the file record header are used to store Diskeeper information.
Diskeeper never defragments or moves files that are specifically stored at a specific physical location on the
volume.
If anything causes your computer to crash while Diskeeper is running, or if you abort the Diskeeper
defragmentation run in the middle of the file relocation process, no data is ever at risk.
Performance
When running in the Automatic Defragmentation mode, Diskeeper is designed to run in the background,
without adversely affecting performance of your Windows computer. The exclusive InvisiTasking technology
ensures Diskeeper keeps your volumes at peak performance without negatively impacting system performance
while it is running. Diskeeper was designed in such a way to ensure it will not interfere with other processes on
your Windows computer.
Process Live Disks
It is not acceptable to force users off the disk while performing routine defragmentation. To do so would be a
case of the cure being worse than the disease. Access to fragmented files is better than no access at all.
The best solution is to defragment online with users active on the same disk volume. Diskeeper was designed
with this in mind. During most of the time Diskeeper is processing a file, it shares the file with any other users
that may access the same file. The last step of processing the file, however, involves locking the file for a very
brief period, a matter of milliseconds. If another user requests a file that Diskeeper has locked, that request is
suspended for the brief period until Diskeeper releases the file. Then the request is serviced. There is never an
interruption of either process as a result of this delay.
This solution allows Diskeeper to defragment open files safely, regardless of whether they are open for read
operations or for write operations.
No Operator Intervention
In keeping with the design goals, after Diskeeper has been started in the Automatic Defragmentation mode, it
runs automatically in the background, without the need for operator intervention. It runs indefinitely, unless
told otherwise by you.

Glossary
access: To store data on, or retrieve data from, a disk drive or other peripheral device. See also file.
administrator: See system administrator.
applet: A small application program that is usually built into an operating system or a larger application
program. For example, the built-in writing and drawing programs that come with Windows are sometimes
called “applets.”
application: A computer program, which causes a computer system to perform some useful work for the user.
ATA: Advanced Technology Attachment. One of several standard types of interfaces used to connect a disk
drive and a computer. See also PATA and SATA.
AutoPlay: A feature of some Windows applications on CD-ROM that causes the program to start automatically
when the CD-ROM is placed in the drive.
background processing: The execution of certain operations during momentary lulls in the primary
(foreground) process. An example of a background process is printing while a word processor is waiting for
keystrokes.
binary: From Latin “bini,” meaning two by two and “ary,” meaning of, or pertaining to. Computers use the
binary number system, which is a way of counting in which only two digits (0 and 1) are used. Contrast with
the familiar decimal number system, in which we count with 10 digits (0 through 9).
bit: Short for binary digit. The smallest unit of information handled by a computer. Like a light switch, a bit is
either on or off, which corresponds to a numerical value of one or zero. Larger numbers are expressed by
groups of bits. See also byte.
boot: Refers to the initial start-up of a computer, such as when you turn on the computer’s power. From the
word “bootstrap,” indicating the computer “lifts itself by the bootstraps;” that is, it gets itself going.
boot-time: The time during which a computer boots; that is, the computer is starting up and the operating
system has not yet taken over control of the computer.
browser: A software program, such as Microsoft’s Internet Explorer, designed to locate and view Web pages
on the Internet. In addition to displaying text, modern browsers also can display pictures and play sounds.
byte: A group of eight bits, which can represent a number from zero through 255, a letter of the alphabet, or a
variety of other things.
cache: From the French word cacher, meaning “to hide.” A temporary storage facility designed to speed things
up by providing information to software that would otherwise have to be obtained from a slower medium.
Caches exist for Web browsers, disk drives and CPUs. See also cache memory.
cache coherency: A condition where the data contained in the cache memories in a computer with multiple
processors is kept consistent at all times.
cache memory: In computers, a cache is a small amount of very fast memory that is placed close to (or inside)
the CPU chip, in order to improve performance. The cache memory holds copies of recently accessed data.
Because computer programs often run the same instructions repeatedly, many times the CPU will find the data
it needs in the cache and therefore will run faster because it does not need to access the computer’s main
memory.
CD-ROM: Compact Disk Read-Only Memory. A stiff plastic disk commonly used by software manufacturers
to distribute software to customers. As the name implies, the original contents of a CD-ROM cannot be
changed.
58
Glossary
central processing unit (CPU): The part of the computer hardware that controls the computer’s overall
operation and performs computations. Most modern CPUs are built into a single integrated circuit or chip. See
also Pentium, x86.
chip: See integrated circuit.
CHKDSK: A program (supplied with Windows NT, Windows 2000, Windows XP, and Windows Server
2003) that checks the integrity of a disk and corrects disk errors such as lost clusters. See also scandisk.
client: In a computer network, a computer that uses the services of another computer, called a server. For
example, a client can “ask” a server to provide it with needed data, or to print a file for the client. See also
server, workstation.
cluster: Smallest addressable unit of space on a disk. A one-byte file will actually use a cluster of disk space.
The minimum size of a cluster depends on the size of the disk volume. The FAT file system allows a maximum
of 65,536 clusters per volume, which means that the cluster size on a 64-megabyte disk volume is one kilobyte,
while a 128-megabyte volume uses two-kilobyte clusters. Thus, the FAT file system can be very wasteful of
disk space on large volumes. The NTFS file system does not suffer from this limitation.
COM: Acronym for Component Object Model, a specification developed by Microsoft for building software
components that can be made into programs or add functionality to existing programs running on Microsoft
Windows platforms.
component: A small modular program that performs a specific function and is designed to work interactively
with other components and applications. See also applet, COM.
contiguous: Adjacent; placed one after the other. A contiguous file is not fragmented; that is, it takes up a
single “chunk” of disk space. See also fragmentation, defragmentation.
control file: A file (Diskeep.ctl) used by Diskeeper to keep track of and control defragmentation of disk
volumes.
controller: A specialized electronic circuit, which serves as an interface between a device, such as a disk drive,
and a computer. See also IDE, SCSI.
CPU: see central processing unit.
CPU priority: To further lessen the impact on a system when defragmenting, Diskeeper provides five
adjustable CPU Priority settings for Manual Defragmentation jobs. The default for Manual Defragmentation
jobs is “Normal” which is the mid-level CPU base priority as assigned by the operating system.
data: Information, as processed by a computer. Plural of the Latin word datum, meaning an item of
information.
database: A collection of related information about a subject, organized in a useful manner that provides a base
or foundation for procedures such as retrieving information, drawing conclusions, and making decisions.
datum: Singular of data.
defragmentation: The reduction or elimination of fragmentation, by making files and/or free disk space more
contiguous.
device: A machine, such as a printer or a disk drive.
digit: From Latin “digitus,” meaning finger. Any of the numbers 0 through 9 in the decimal number system,
called a digit because people originally used their fingers for counting. Computers use a binary number system
with only two digits (0 and 1).
directory: A file that contains a catalog of files and other directories stored on a disk, which allows you to
organize your files into groups, making them easier to find. Equivalent to folder.
Glossary
59
directory consolidation: A Diskeeper feature which, at boot-time, gathers (almost) all directory entries on a
volume into a single area on the disk, instead of scattered in many places. Directory consolidation requires
sufficient contiguous free disk space into which the directories can be moved.
disk drive: A device containing one or more disks, treated as a unit by a computer.
Diskeeper: A software product that increases system performance through disk defragmentation. It eliminates
resource-wasting file fragmentation safely, by consolidating fragmented files and free space.
diskette: See floppy disk.
domain: In Windows NT, Windows 2000, Windows XP, Windows Server 2003, and Windows Vista™ a group
of workstations and servers, defined by an administrator, that share a common directory database and allow a
user to log onto any resource in the domain with a single user ID and password. Each domain in a network has
a unique name.
drive: See disk drive.
drive letter: In Windows and MS-DOS operating systems, the naming convention for disk drives, consisting of
a letter, followed by a colon. Drives A: and B: are normally reserved for floppy disk drives and C: typically
indicates the first hard drive. See also volume.
encrypted file: A file that has been scrambled and made unrecognizable by anyone who does not have the
proper “key” to decode it. The Windows Encrypting File System (EFS) allows users to encrypt files and folders
on an NTFS volume to prevent access by unauthorized individuals.
event logging: The process of recording audit information when certain events occur, such as services starting
and stopping, users logging on and off and accessing resources. Logged Diskeeper events can be viewed with
the Event Viewer utility (in Administrative Tools.)
Event Viewer: A utility that is part of the Administrative Tools available in Windows, which permits the
viewing of logged events. See also event logging.
extended partition: A type of partition that permits the limitation of four partitions per disk drive to be
overcome. A disk drive may be partitioned into a maximum of four primary partitions, or three primary
partitions plus an extended partition. One or more logical drives may be created within an extended partition.
FAT: See file allocation table.
FAT file system: The file system used by MS-DOS and adapted for Windows to store information on disks,
which makes use of a file allocation table. There are three types of FAT file system. The FAT12 (12-bit) is
used on FAT volumes smaller than 16 megabytes in size, such as floppy disks—it is not supported by
Diskeeper. FAT16 can be found on all versions of Windows from Windows 95 through Windows Vista.
Windows Vista, Windows Server 2003, Windows 2000, Windows Me, Windows 98, and the later OSR 2
version of Windows 95 also support FAT32; Windows NT does not.
field: A subdivision of a record in a file. For example, a record in a customer file may contain a name field, an
address field and a phone number field.
file: A complete, named collection of data, such as a program, a set of data used by a program, or a usercreated document. See also record, field.
file allocation table (FAT): A table or list maintained by some operating systems, to keep track of how files
are stored on a disk.
file system: The method used by an operating system, of naming, accessing and organizing files and directories
on a disk. See also NTFS, FAT file system.
floppy disk: A removable storage medium, consisting of a small magnetic disk made of flexible plastic, housed
in a square protective envelope or cartridge. Originally, floppy disks really were “floppy,” because they were
enclosed in a paper envelope. Also called a diskette, which is a better name for the more recent design that uses
a stiff plastic cartridge. Contrast with hard disk.
60
Glossary
folder: A file that contains a catalog of files and other directories stored on a disk, which allows you to
organize your files into groups, making them easier to find. Equivalent to directory.
formatting: A method of preparing a disk surface for use by placing certain magnetic patterns on it, which are
used by the file system in storing and retrieving data.
fragmentation: The word fragmentation means “the state of being fragmented.” The word fragment means “a
detached, isolated or incomplete part.” It is derived from the Latin “fragmentum,” which in turn is derived from
“frangere,” meaning “break.” So, fragmentation means that something is broken into parts that are detached,
isolated or incomplete.
gigabyte: A measure of computer storage capacity equal to approximately a billion bytes. A gigabyte is two to
the 30th power, or 1,073,741,824 bytes.
graphical user interface (GUI): Pronounced “gooey.” A user interface, as used in the Windows operating
systems, which uses a mouse and graphic displays to interact with the user, with the purpose to make the
computer system easier to use than other operating systems, such as MS-DOS.
GUI: See graphical user interface.
hard disk: One or more rigid metal platters, coated with magnetic material. Contrast with floppy disk, or
diskette, which is made of plastic. Also used to refer to the physical unit that makes up a disk drive.
hardware: The physical parts of a computer system, including devices such as printers and disk drives.
Contrast with software.
I-FAAST: A Diskeeper exclusive, Intelligent File Access Acceleration Sequencing Technology (I-FAAST)
improves file access and creation on NTFS volumes by up to 80% (average 10%-20%) above and beyond the
improvement provided by defragmentation alone. This is the first industry implementation of “Disk
Performance Calibration”, the modern evolution of the outdated and inconclusive disk optimization strategies
of the past.
InvisiTasking: A proprietary technology developed by Diskeeper Corporation that carefully monitors resource
consumption on a Windows computer system and injects Diskeeper processing into the unused portions—and
only into the unused portions. InvisiTasking is so good that it is all but impossible to even detect whether
Diskeeper is running.
I/O Smart: The Diskeeper I/O Smart feature intelligently monitors drive access during defragmentation to
ensure top system speed. When this option is selected, Diskeeper will temporarily suspend defragmentation
whenever other disk activity needs to occur (I/O throttling). This proprietary technology detects whether or not
the disk is busy with other I/O requests and pauses defragmentation to eliminate any potential interference with
user or system needs at the “disk” level.
IDE: Integrated Device Electronics. One of several types of interfaces between a disk drive and a computer,
where the controller is built into the disk drive, which eliminates the need for a separate controller card in the
computer. See also ATA and SCSI.
integrated circuit: Also called a chip. A collection of electronic parts with a specific purpose, built into a
single physical package. See also central processing unit.
Intel: Manufacturer of processor chips, known especially for the Pentium and x86 processors.
interface: The connection and interaction between hardware, software and/or the user. For example, a disk
controller provides a physical interface between a computer and a disk drive. The keyboard, mouse and display
are an interface between a computer and the user.
Internet: A global network that links millions of computers. One popular section of the Internet is the World
Wide Web, which allows computer users to view text and pictures with the aid of a browser, such as Internet
Explorer. E-mail (electronic mail) is another popular part of the Internet, which allows computer users to send
and receive written messages.
Glossary
61
Internet Explorer: A software package developed by Microsoft for browsing the Internet, but increasingly
used with other applications.
job: A request to have the computer or its peripherals perform some activity. In relation to Diskeeper, it is a
request to have a disk defragmented.
log file: A file that keeps track of certain events as they occur. Windows maintains several log files that can be
viewed with the Event Viewer.
logical drive: That portion of the space on a disk drive that is considered by the software to be a single unit. In
this context, logical means “conceptual.” because there is no direct relationship between the name and a
physical object. See also partition, volume.
long filenames: In the DOS operating system, filenames were limited to a maximum of eight characters,
followed by a period and up to three characters to indicate the type of file. This is also referred to as the 8.3 file
naming convention. The Windows 98/Me, Windows NT, Windows 2000, Windows XP, and Windows Server
2003 operating systems allow filenames that are over 200 characters long. In addition, these filenames may
contain a mixture of upper- and lowercase characters and embedded spaces.
master file table (MFT): On an NTFS volume, the master file table is a file, which contains information about
all other files in that volume. This includes the name of each file, its physical location on the disk, and other
information.
media: A collective word for the physical material on which computer-based information is stored, such as a
CD-ROM or floppy disk. Media is the plural of medium, but like data is often used in the singular form.
medium: See media.
memory: The computer’s temporary working storage, where program instructions and data are kept,
permitting the CPU to process the instructions.
MFT: See master file table.
Microsoft: A computer software company, with its head office in the state of Washington; creators of the MSDOS and Windows operating systems.
MMC: Microsoft Management Console. MMC can be used to create, save and open administrative tools
(called snap-ins), such as Diskeeper. MMC provides a common user interface for system tools, as well as a
system for managing hardware, software and network components.
MS-DOS: Microsoft Disk Operating System. An operating system designed for a small computer with a single
user running one application program at a time.
multitasking: A feature of an operating system, where the computer can work on more than one task at a time.
See also background processing.
network: A group of computers that are connected together and capable of exchanging data with each other.
See also server, client.
NTFS: New Technology File System. A file system designed specifically for use with Windows NT, and
carried into Windows 2000, Windows XP, and Windows Server 2003.
OEM: Acronym for original equipment manufacturer. The term is misleading, because an OEM typically buys
computers from another manufacturer, customizes them for a particular application, and then sells them under
the OEM’s own brand name.
operating system: A collection of programs, which perform system functions and control the running of
application programs and the allocation of resources.
page file or paging file: An area of a disk that is set aside to hold data intended to reside in the computer’s
memory. Portions of the paging file are copied to memory as needed. This mechanism requires a much smaller
amount of physical memory than would be required if the entire program were to be loaded into memory all at
once. See also swap file.
62
Glossary
partition: A subdivision of the space on a disk drive that is treated as though it were a separate physical unit. A
computer with only one hard disk drive can have a single partition, often called drive C:, or it can have several
partitions, such as drive C:, drive D:, and drive E:. See also volume, drive letter, primary partition, extended
partition, logical drive.
PATA: Parallel Advanced Technology Attachment. Originally called ATA, but retroactively renamed PATA
with the introduction of Serial Advanced Technology Attachment (SATA) interfaces. One of several methods
of interfacing disk drives and other devices to computers. See also ATA, IDE, SATA and SCSI.
Pentium: The name of a type of processor, introduced by Intel in 1993. It is the successor to the 80486 and
equivalent to the 80586 chip in the x86 series.
peripheral device: (Related to periphery, roughly meaning “on the outside.”) A device, such as a disk drive,
printer, keyboard or mouse, connected to and used by a computer.
permission: The ability of a user on a computer system to access or modify files, especially those that he or she
did not create. Permissions exist for security reasons, to prevent unauthorized access to sensitive information.
The system administrator assigns permissions, or “who has access to what.”
platform: The environment, in which a computer system operates, either based on the computer’s CPU or its
operating system. For example: the x86 platform, or the Windows Server 2003 platform.
platter: A disk drive consists of one or more platters, each of which can receive magnetic recordings on both
sides. The platter spins like a phonograph record on a turntable.
primary partition: In Windows and MS-DOS operating systems, the disk space on a disk drive may be divided
into a maximum of four primary partitions; or three primary partitions plus an extended partition, which in turn
can contain one or more logical drives.
priority: On a Windows system, several programs can appear to be running at once, even though the CPU can
only process one instruction at a time. With the help of the operating system, the CPU processes a few
instructions from one program, then a few instructions of the next program, and so on, over and over. Without
priority assignments, each program would be given about the same amount of time in each “time slot.” but by
assigning priorities, the more important programs can be given longer time intervals than the less important
ones, allowing them to complete faster.
process: A program, along with the system resources the program requires to run. A process represents a unit
of resource ownership and work to be done. The operating system creates processes to keep track of resources
and to ensure the proper scheduling of tasks.
processor: See central processing unit.
program: A set of instructions that tell a computer what to do. Synonym: software.
RAID: Redundant Array of Independent Disks. A method of combining several disk drives to make one large
volume. Typically used on a network file server to achieve faster access, greater protection against disk failure,
or both.
record: A collection of related data items, treated as a unit. For example, in a file containing information about
a company’s customers, one record would consist of the particulars (name, address, phone number, etc.) of one
customer. See also field.
registry: A database that contains information about current hardware settings, installed software, user
preferences and associations between file types, and applications that access those files.
resource: Any part of a computer system, such as a disk drive, printer, or memory, which can be used by a
program.
SATA: Serial Advanced Technology Attachment. A successor to ATA (which was later renamed PATA). One
of several methods of interfacing disk drives and other devices to computers. See also ATA, IDE, PATA and
SCSI.
Glossary
63
SCSI: Small Computer System Interface. One of several methods of interfacing disk drives and other devices to
computers. See also ATA, IDE, PATA, and SATAI.
server: On a computer network, a computer that makes resources available to other computers (clients or
workstations.) For example, all the computers on a network can be set up to share a single high-speed printer,
which is connected to the server. Usually, the server is faster and more powerful than the client computers
connected to it.
service: A process that performs a specific system function and often provides an application programming
interface (API) for other processes to call. Diskeeper uses a Windows service, which allows Diskeeper to run in
the background while other applications are running.
Service Pack: A collection of software used to issue corrections and updates to software between major
releases. Usually refers to compilations of corrections and updates to a Windows operating system.
Set It and Forget It: A term that was created by Diskeeper Corporation, which is a registered trademark and
hallmark of the company. A “Set It and Forget It” product can operate transparently (unseen by the user) and in
the background (concurrent with other applications). A Set It and Forget It product runs without further
intervention or attention from the user or administrator.
SMS: System Management Server. A software product from Microsoft, which permits the system administrator
on a Windows NT, Windows 2000 or Windows Server 2003 network to do such things as install and run new
software on different computers on the network, all from a single location.
snap-in: A program, such as Diskeeper, that can be used with the Microsoft Management Console (MMC). For
more information, see the MMC Help facility.
software: A generic term for computer programs, taken collectively. Contrast with hardware. Software can be
categorized into application software and system software.
sparse files: A method of storing large files—that contain mostly empty space and not much data—in a way
that uses much less disk space than would otherwise be used. Sparse file support allows an application to create
very large files without committing disk space for every byte.
swap file: A file on a disk drive that Windows 98/Me uses to hold temporary data that will not fit into memory.
When needed, the operating system moves data from the swap file to memory. See also paging file.
system: The collection of one or more computers and peripheral devices. Sometimes used as a synonym for
operating system, or the combination of hardware and software, as a logical unit.
system administrator: The person in charge of maintaining a multi-user computer system.
system file: In general, a file that is part of, or accessed by, the operating system. The Diskeeper Volume Map
display shows certain system files in green, particularly the master file table (MFT) and several other files that
cannot be moved safely by Diskeeper (or any other defragmenter). These are not the files that make up the
Windows operating system, but the files that make up the NTFS file system.
task: A program or portion thereof that is run as an independent entity.
terabyte: A measure of computer storage capacity equal to 2 to the 40th power or approximately a thousand
billion bytes (or a thousand gigabytes).
trialware: A free software package from Diskeeper Corporation, such as Diskeeper, that has the same
functionality as the official version of the software, but which works for a limited time period, after which it
expires. Trialware allows you to try the software before making a buying decision.
utility: A program that provides basic services or functions.
volume: A subdivision of the space on a disk drive that is treated as though it were a separate physical unit, or a
combination of physical disks treated as a single unit. A computer with only one hard disk drive can have a
single volume, often called drive C:, or it can have several volumes, such as drive C:, drive D:, and drive E:.
See also drive letter, logical drive, partition.
64
Glossary
volume set: In Windows, a single logical drive, which is composed of up to 32 areas of free space on one or
more disk drives. Volume sets can be used to combine small areas of free space on one or more disk drives into
a larger logical drive, or to create a single large logical drive out of two or more small disks.
Windows: A family of operating systems, first introduced by Microsoft in 1983, with a graphical user
interface and which ran on MS-DOS based computers. See also Windows 95, Windows 98, Windows NT,
Windows 2000, Windows XP, Windows Server 2003 and Windows Vista.
Windows 2000: Originally named Windows NT 5.0, Windows 2000 is a family of operating systems for
desktop computers and network servers, announced by Microsoft in 1998. Windows 2000 resembled Windows
NT 4.0 and Windows 98, but had many enhancements and new features. Windows 2000 is available in several
editions, ranging from Windows 2000 Professional to Windows 2000 Advanced Server.
Windows 95: A version of Windows released in 1995. New features in Windows 95 with regard to its
predecessor, Windows 3.1, included a new user interface and support for 32-bit applications.
Windows 98: Successor to the Windows 95 operating system, Windows 98 featured support for the FAT32 file
system, greater Internet integration, and support for the latest (at the time) hardware developments.
Windows Me: Short for Windows Millennium Edition, an operating system released by Microsoft in
September 2000. Successor to Windows 98 and designed for home use, Windows Me offers enhancements in
the areas of digital media, user interface, home networking, and the Internet.
Windows NT: An operating system released by Microsoft in 1993 (NT stands for New Technology.) It has a
similar graphical user interface to Windows, but it does not run over MS-DOS and was designed specifically
for computer network environments.
Windows Server 2003: An operating system released by Microsoft in 2003 as the follow-up version to
Windows 2000 Server. Like its predecessor, it has a similar graphical user interface to Windows, but it does not
run over MS-DOS and has been designed specifically for computer network environments. Windows Server
2003 is available in Standard, Web, Enterprise, and Datacenter editions.
Windows Vista: Previously known by the codename of “Longhorn”, Windows Vista is an operating system
expected to be released by Microsoft in 2006 or 2007 as the follow-up version to Windows XP. It has an
updated graphical user interface as well as a number of other anticipated improvements. Windows Vista is
slated to be available in several editions for corporate and personal use.
Windows XP: An operating system released by Microsoft in 2001 as the follow-up version to Windows 2000.
Like its predecessor, it has a similar graphical user interface to other Windows versions, but it does not run
over MS-DOS and has been designed specifically for computer network environments. Windows XP is
available in several editions for different uses, such as Windows XP Professional for corporate use, or
Windows XP Home Edition for home users.
workgroup: In Windows NT, Windows 2000, Windows XP, or Windows Server 2003, a workgroup consists of
one or more computers that do not participate in a domain and are therefore responsible for their own security
and administration.
workstation: A computer that has been set up for use by an individual typically connected to a network. The
term is also used to indicate a client computer, in contrast with a server.
x86: Symbol to represent a series of CPUs, manufactured by Intel and others, including model numbers 8086,
80286, 80386, 80486 and 80586 (Pentium). All of the CPUs in this series have certain characteristics in
