EZ-Drive Quick Installation
WD Caviar Series 3.5-Inch EIDE Hard Drives
EZ-DRIVE SOFTWARE OVERVIEW
If you did not receive the EZ-Drive software, you can download it from our web site at www.wdc.com.
EZ-Drive software is included with the Western Digital hard drive to help you:
Quickly and easily partition and format your new hard drive.
Overcome the 528 MB barrier.
Overcome the 2.1 GB barrier.
Partitioning and Formatting
Your WD Caviar drive has been low-level formatted at the factory.
The hard drive is defect-free and ready to set up. You must partition and high-level format the drive so it can accept files.
There are two ways to format and partition your hard drive.
1. Use the EZ-Drive software that you received with the hard drive.
2. Use the DOS utilities FDISK and FORMAT.
We recommend using EZ-Drive. It is a safe, fast, and an easy way to partition and format the hard drive. See the section Using EZ-Drive
Software on page 2 for instructions.
For instructions on using FDISK and FORMAT, see your DOS user manual.
Note: DOS has a 2.1 GB partition limit. If you have a 2.5 GB or larger hard drive, you must create at least two partitions to access the full capacity.
Partition and Format
If your system supports the full capacity of the hard drive, EZ-Drive will only partition and format the hard drive. It does not install code on your boot sector.
528 MB Barrier
Most computer systems built before August 1994 do not support hard drives larger than 528 MB unless the BIOS is updated or third-party software such as EZ-Drive is installed.
2.1 GB Barrier
Some computer systems built before early 1996 do not support hard drives with more than 4095 cylinders (hard drives larger than 2.1
GB) unless the BIOS is updated or third-party software such as
EZ-Drive is installed.
EZ-Drive Help Files
To access EZ-Drive help files on the installation disk, select
Installation Help from the EZ-Drive main menu.
Compatibility
You can use EZ-Drive software with DOS 5.0 and above, Windows
3.1x, Windows for Workgroups, Windows 95, Windows NT, OS/2
2.1X, and OS/2 Warp.
You cannot use EZ-Drive with Novell NetWare or Unix.
Data Compression Software
EZ-Drive is compatible with Stacker, Drivespace, and Doublespace disk compression utilities. Other data compression software may not be compatible. Always back up your data before using any data compression software.
Hard Disk Device Drivers
Products that use their own hard disk device drivers, such as third-party disk controllers, may not be compatible with EZ-Drive.
Memory Managers
EZ-Drive is fully compatible with the standard memory managers that come with DOS and Windows. However, EZ-Drive loads in conventional memory and may not be compatible with some third-party memory managers.
Ontrack Disk Manager and EZ-Drive
Ontrack Disk Manager and EZ-Drive cannot co-exist in the same system. If your existing drive has Ontrack Disk Manager installed and multiple partitions, you cannot install EZ-Drive. We recommend using Ontrack Disk Manager to set up the new hard drive.
If your existing drive has Ontrack Disk Manager installed and only one partition, you can either use EZ-Drive to convert the Ontrack
Disk Manager partition or use Ontrack Disk Manager to set up the new drive. During installation, EZ-Drive detects Ontrack Disk
Manager and prompts you to convert the partition to an EZ-Drive partition. If you do, EZ-Drive converts the Ontrack Disk Manager partition to an EZ-Drive partition.
Even though EZ-Drive can convert your Ontrack Disk Manager partition to an EZ-Drive partition without data loss, Western Digital recommends that you back up your data before selecting this option.
Note: EZ-Drive can convert single Ontrack Disk Manager partitions only. It cannot convert multiple Ontrack Disk Manager Partitions.
BEFORE YOU BEGIN
Back up the data on your existing hard drive.
Make sure you have a bootable DOS system disk or Windows 95
Startup disk, EZ-Drive, DOS, and operating system software, and your system manual.
Write down the hard drive type and parameters (cylinders/ heads/sectors) for the existing drive. Do NOT change the parameters of your existing hard drive.

CMOS SETUP
Most computer systems provide a CMOS setup program that gives you access to information regarding your system configuration. Refer to your system manual for CMOS setup instructions.
Note: Each BIOS is different. The information supplied here is not meant to be followed step-by-step; it is provided as a guideline. Consult your system manual for details.
Before installing EZ-Drive, go into your CMOS setup and select the hard drive type option.
The following hard drive types are usually offered in CMOS: auto
config, predefined, and user defined.
Auto Config Drive Type
Western Digital recommends selecting the auto config drive type. The
auto config drive type automatically sets up the Western Digital hard drive parameters. If you encounter problems using auto config, try selecting Type 01.
If you select auto config and have a translating BIOS, EZ-Drive will not install. You can, however, use EZ-Drive to partition and format your hard drive.
Note: Even if your BIOS correctly detects the parameters, this doesn’t mean that the BIOS can translate those parameters. If you are in doubt, we recommend contacting your system or BIOS manufacturer.
Predefined Drive Type
If you do not have the auto config drive type or if you encounter problems after selecting auto config, select the Type 01 drive type.
Selecting Type 01 ensures that EZ-Drive will install on your hard drive.
User Defined Drive Type
Select user defined if your CMOS Setup does not offer auto config or
Type 01. If you select user defined, you must enter 1023x16x63 for your drive parameters.
USING EZ-DRIVE SOFTWARE
Follow these instructions to partition and format the new hard drive.
If your system does not support the full capacity of your hard drive,
EZ-Drive installs special code in the boot sector of the hard drive to overcome the BIOS limitations.
Note: The steps outlined in this section represent a typical installation.
You installation may vary.
If your system does support the full capacity of your hard drive,
EZ-Drive will only partition and format your hard drive. It will not install code on your boot sector.
CAUTION: Installing EZ-Drive on any drive that contains software and data will result in the erasure of all software and data on that drive.
1. After you complete CMOS setup, insert a bootable DOS disk or
Windows 95 startup disk in drive A.
2. Press
CTRL+ALT+DEL
to reboot your system.
3. Insert the EZ-Drive disk in drive A. At the A: prompt, type ez and press

FREQUENTLY ASKED QUESTIONS
A short list follows with common questions and solutions.
Q: Do I need to run FDISK and FORMAT?
A: No. EZ-Drive is a faster, easier way to partition and format your hard drive.
Q: I don’t see the full capacity of my hard drive when installing
DOS.
A: Two issues affect the installation of your hard drive: 1) some systems do not properly recognize hard drives that have more than
4095 cylinders (drives larger than 2.1 GB); 2) most system BIOS dated before 1994 don’t recognize drives greater than 528 MB. To overcome this limitation, either install EZ-Drive or upgrade your system BIOS. The following list provides the phone numbers for common BIOS sources.
-OR
If you installed EZ-Drive and then incorrectly booted to your DOS installation disks, you may have accidentally used DOS to overwrite your EZ-Drive partitions. You need to use FDISK to delete your
DOS partitions and then re-install EZ-Drive. Be sure to follow the instructions outlined in the preceding section Installing an Operating
System from Disk.
The following list provides the phone numbers for several BIOS sources.
BIOS Sources:
Micro Firmware
(Phoenix BIOS only) (405) 321-8333
Phoenix (617) 551-4000
Unicore (508) 686-6468
79-850080-000 S0220 3-97 4
Q: Will my system BIOS support the Western Digital 2.5 GB or larger hard drive?
A: With some systems, the BIOS cannot recognize drive capacities greater than 2.1 GB. Use the EZ-Drive software to overcome this
BIOS limitation.
Q: The reported capacity of my hard drive is MUCH smaller than
Table 1 shows it should be.
A: Your system BIOS improperly handles hard drives that report greater than 1024 cylinders. Use the EZ-Drive software to access the full capacity of your drive.
Q: What will happen if I install EZ-Drive on a hard drive that has
Ontrack Disk Manager?
A: EZ-Drive and Ontrack Disk Manager cannot coexist in the same system. If the existing hard drive has only one partition and Ontrack
Disk Manager already installed, EZ-Drive converts the Ontrack Disk
Manager partition to an EZ-Drive partition. Back up your hard
drive before installing EZ-Drive. If the existing hard drive has multiple partitions and Ontrack Disk Manager installed, EZ-Drive will not install. Use Ontrack Disk Manager to set up the new hard drive.
Q: How much memory does EZ-Drive use?
A: 5 KB.
Q: How can I get 32-bit disk access in Windows?
A: Use the 32-bit disk access driver included on the EZ-Drive disk.
Install the driver by running the EZ-Drive SETUP.EXE program.
Q: I have a 2.5 GB or larger drive. Can I create one partition only?
A: No. DOS has a 2.1 GB partition limitation. You must have at least two partitions to access the full capacity of your drive.
