Internal tape drives come in two mounting configurations,
one for 3.5-inch half-height bays and one for 5.25-inch halfheight bays. These two drives are identical, except that the
drive designed for 5.25-inch installations has mounting
brackets on each side of the drive and a different front bezel.

What Else You Need
What Else You Need
2
In addition to the contents included with your internal tape drive, you
need the following items to install your internal tape drive.
•
A SCSI host bus adapter that is properly installed and configured in a
host computer
•
A 3.5-inch or 5.25-inch half-height bay
•
A SCSI ribbon cable
•
Backup application software that supports the internal tape drive.
For a list of the latest backup software applications tested with the
internal DDS-4 and DAT 72 tape drives, please visit our Web site at
www.quantum.com/support.
Avoiding Electrostatic Damage
2
Your internal tape drive has very sensitive components that are prone to
damage from electrostatic discharge (ESD). Use extreme care when
handling the drive, as it can be damaged by ESD.
Before handling the drive, read these ESD instructions to prevent damage
to the drive.
•
Wear an ESD-preventive grounding wrist strap or observe similar
ESD precautions when working with the drive. Be sure the wrist
strap makes good skin contact. Do not remove the wrist strap until
you finish working with the drive.
•
Avoid contact between the drive, other equipment, and clothing. The
wrist strap only protects the equipment from ESD voltages on the
body; ESD voltages on clothing can still cause damage.
•
When the drive is not being used, keep it in its antistatic bag.
•
Before you remove the drive from the antistatic bag, touch a metal or
grounded surface to discharge any static electricity buildup from
your body.
DDS-4/DAT 72 User’s Guide
11
Chapter 2 Installing Internal Tape Drives
Installation Summary
•
Hold the drive by its edges only. Avoid touching any exposed parts
on the printed circuit board.
•
Always place the drive on top of or inside the antistatic bag to reduce
the chance of ESD damage.

Your internal tape drive comes with various default settings. These
settings are configured using jumpers and switches.
•
Jumpers are located on the back of the drive, between the SCSI
interface and power connectors
•
Switches are located on the underside of the drive. If you change a
switch setting, you must turn the drive off and then on to have the
new setting take effect.
You may need to change these settings to suit your requirements. Review
the default settings in table 2 to determine whether they suit your
requirements or need to be changed.

Note:
You can also change SCSI IDs by connecting a SCSI addressselection switch to pins 1 through 8.
If you change the drive’s default SCSI ID, avoid using SCSI IDs
0 and 1 (which typically are assigned to a boot drive) and SCSI
ID 7 (which typically is assigned to SCSI controllers or host bus
adapters).

Parity Checking 2
Jumper Pins 9–10:
Pins 9-10 shunted: Enable parity checking (default)
Pins 9-10 open: Disable parity checking
By default, parity checking is enabled on the internal tape drive. To
disable parity checking, remove the jumper from pins 9 and 10.
Note:
Terminator Power 2
If you disable parity checking, the drive still generates a parity
bit.
Jumper Pins 11–12:
Pins 11-12 shunted: Enable terminator power
Pins 11-12 open: Disable terminator power (default)
By default, terminator power is disabled on the internal tape drive. To
enable terminator power, place a jumper across pins 11 and 12.
Note:
Data
Compression
If you enable terminator power, be careful not to short the
TERMPWR signal to ground (for example, by attaching the
SCSI cable upside down). If a short occurs, terminator power to
the bus is interrupted. After the short is removed, a fuse in the
drive is automatically reset, restoring terminator power.
Settings:
2
Switch 1 ON = Enable hardware data compression (default)
Switch 1 OFF = Disable hardware data compression
Switch 2 OFF = Recognize SCSI data compression commands (default)
Switch 2 ON = Ignore SCSI data compression commands
The internal tape drive provides two switches for controlling data
compression.
Switch 1 determines whether hardware data compression is enabled or
disabled. By default, switch 1 is set to ON, enabling hardware data
compression. To disable hardware data compression, set switch 1 to the
OFF position.
DDS-4/DAT 72 User’s Guide
17
Chapter 2 Installing Internal Tape Drives
Reviewing Drive Default Settings
Switch 2 controls whether SCSI commands are recognized for enabling or
disabling hardware data compression. By default, switch 2 is set to ON,
allowing SCSI commands to be used to enable or disable hardware data
compression. To prevent SCSI commands from enabling or disabling
hardware data compression, set switch 2 to the OFF position.
When data compression is enabled, the drive compresses all data written
to tape and decompresses all compressed data read from tape. The degree
of compression varies due to the type of data being processed.
Media Recognition
System (DDS-4

2
•
Data with a high degree of redundancy, such as structured database
files or graphics files, are compressed most efficiently, often at a ratio
of 2:1 or more.
•
Data with little redundancy, such as executable programs, are
compressed the least.
Settings:
Switch 3 ON = Enable MRS (default)
Switch 3 OFF = Disable MRS
Using non-DDS media may appear to give satisfactory results, but the
inferior specifications of such media can cause data-integrity problems.
To avoid these problems, the internal tape drive provides a mediarecognition system (MRS) feature that determines whether tape
cartridges conform to the DDS tape standard.
By default, switch 3 is set to ON, enabling MRS. With this setting, the
drive:
•
Reads from and writes to MRS media.
•
Reads from but does not write to non-MRS media.
To disable MRS, set switch 3 to the OFF position. With this setting, the
drive reads from and writes to MRS and non-MRS media.
Note:

Switch 4 enables or disables the Power-On Self-Test diagnostics that the
drive performs when powered on. By default, the drive responds to SCSI
commands only after it successfully completes the Power-On Self-Test
(about 5 seconds). To prevent the drive from performing the Power-On
Self-Test when powered-up, set switch 4 to the OFF position.

Narrow SCSI is not recommended.
Switch 9 is reserved on internal DAT 72 drives.
Settings:
Switch 10 ON = Vendor ID is “SEAGATE DAT” (default)
Switch 10 OFF = Vendor ID is “ARCHIVE Python”
Switch 10 determines the vendor ID that the internal tape drive returns
when it receives a SCSI “Inquiry” command. By default, the drive returns
the vendor ID SEAGATE DAT.
Setting switch 10 to the OFF position configures the drive to return the
vendor ID ARCHIVE Python. Independent software vendors can use this
vendor ID to provide software compatibility with previous Quantum
DDS tape drives.
Recording Drive Information

The internal tape drives can be used with two SCSI interfaces:
•
Wide SCSI — either Low Voltage Differential (LVD) or Single-ended
(16-bit Wide mode),
•
Narrow SCSI — either Low Voltage Differential (LVD) or Singleended (8-bit Wide mode).
DDS-4/DAT 72 User’s Guide
25
Chapter 2 Installing Internal Tape Drives
Connecting a SCSI Cable
The tape drive automatically detects whether the SCSI bus is LVD or
single ended. Be sure the SCSI bus is terminated properly.
Note:
Connecting to a
Wide SCSI
Connector
2
We strongly recommend that you attach the tape drive to SCSI
controllers that support the SCSI Ultra2 LVD interface only.
Attaching the tape drive to a non-LVD SCSI controller or an 8bit Narrow SCSI controller will degrade the performance of
your tape drive and backup operations. Performance will also
be degraded if you attach non-LVD SCSI devices on the same
bus cable as your LVD connection. Do not connect the tape
drive to a disk RAID controller (disk RAID controllers are not
supported). If you install an adapter, we recommend you
purchase a SCSI LVD controller kit that includes the SCSI cable
and terminator.
If your computer has a 68-pin wide SCSI connector:
1 Attach the interface cable from the SCSI host adapter to the 68-pin
SCSI interface connector on the back of the internal tape drive.
Figure 8 SCSI

The internal tape drives have an Ultra Wide SCSI interface. Obtaining a
50-to-68 pin adapter lets you connect the 68 pins on the internal tape
drive to the 50 pins on the computer’s narrow SCSI bus.
1 Connect the adapter to your computer’s 50-pin SCSI connector.

2 Connect the SCSI cable with the adapter to the internal tape drive’s
68-pin SCSI connector.
Note:
Be sure the upper 8 data bytes of the 68-pin cable are
properly terminated.
Checking SCSI Termination
2
The internal tape drives do not provide SCSI termination. For this reason,
they should not be the last device on a SCSI chain. Figure 9 shows two
examples of terminating the internal tape drives.
If the drive is the only SCSI device on the bus:
1 Attach it to the next-to-last connector on the SCSI chain.
2 Attach a multi-mode terminator to the last connector in the chain.
This terminator typically is a small, rectangular plastic block that is
marked SCSI Terminator and attaches to the cable.

To complete and test your internal tape drive installation:
1 Use the screws you removed earlier to secure the drive in place.
2 Replace the computer cover.
3 Reconnect the power cord to the computer’s power connector.
4 Turn on the computer. If the internal tape drive is configured to
perform its Power-On Self-Test (see Power-On Self-Test on page 18),
it performs the test for about five seconds. When the drive passes the
test, all three front-panel LEDs should be OFF.

5 Install your backup software program. The documentation that came
with your software should describe this procedure.
6 Gently insert a tape cartridge into the internal tape drive’s slot (see
Loading a Cartridge on page 43). Slide the cartridge into the slot until
the drive accepts the cartridge and loads it. A brief delay occurs while
the drive identifies the cartridge type and state, and moves the tape
to the data area. Then the green Media LED goes ON.
7 Use your backup software application to perform a sample backupand-verify operation. The amber Drive LED goes ON as data is written
to and/or read from the tape.
8 At the end of the operation, press the Eject button on the front of the
internal tape drive to eject the cartridge from the drive (see
Unloading a Cartridge on page 44).

Each SCSI device on the bus must have its own unique ID. Your external
tape drive is shipped with a default SCSI ID of 6. If another SCSI device in
the SCSI chain is already using this ID, use the SCSI ID Selector switch on
the back of the drive to change the drive’s SCSI ID.
Note:
If you change the drive’s default SCSI ID, avoid using SCSI
IDs 0 and 1 (which typically are assigned to a boot drive) and
SCSI ID 7 (which typically is assigned to SCSI controllers or
host bus adapters. If you change the default SCSI ID, turn the
drive power off and back on.

The external tape drives provide two 68-pin, shielded connectors on the
back panel (see figure 11). You can use either connector to attach the drive
to the host computer or to another SCSI device.
The internal tape drives can be used with two SCSI interfaces:
•
Wide SCSI — either Low Voltage Differential (LVD) or Single-ended
(16-bit Wide mode).
•
Narrow SCSI — either Low Voltage Differential (LVD) or Singleended (8-bit Wide mode).
The tape drive automatically detects whether the SCSI bus is LVD or
single ended. Be sure the SCSI bus is terminated properly.
Note:

We strongly recommend that you attach the tape drive to SCSI
controllers that support the SCSI Ultra2 LVD interface only.
Attaching the tape drive to a non-LVD SCSI controller or an 8bit Narrow SCSO controller will degrade the performance of
your tape drive and backup operations. Performance will also
be degraded if you attach non-LVD SCSI devices on the same
bus cable as your LVD connection. Do not connect the tape
drive to a disk RAID controller (disk RAID controllers are not
supported). If you install an adapter, we recommend you
purchase a SCSI LVD controller kit that includes the SCSI cable
and terminator.
If your computer has a 68-pin wide SCSI connector:
1 Turn off your computer.
2 Connect the SCSI cable from the SCSI host adapter or from another
unterminated SCSI device to either of the two 68-pin SCSI connectors
on the back of the external tape drive (see figure 11).
3 If desired, use the other SCSI connector on the back panel of the

To complete and test your external tape drive installation:
1 Reconnect the power cord to the computer’s power connector.
2 Use the On/Off Switch on the back of the external tape drive to turn
on the drive (see figure 11). The external tape drive performs its
Power-On Self-Test for about five seconds. When the drive passes the
test, all three front-panel LEDs should be OFF.
3 Turn on the computer.
4 Install your backup software program. The documentation that came
with your software should describe this procedure.
5 Gently insert a tape cartridge into the external tape drive’s slot. Slide
the cartridge into the slot until the drive accepts the cartridge and
loads it. A brief delay occurs while the drive identifies the cartridge
type and state, and moves the tape to the data area. Then the green
Media LED goes ON.
6 Use your backup software application to perform a sample backupand-verify operation. The amber Drive LED goes ON as data is
written to and/or read from the tape.
7 At the end of the operation, press the Eject button on the front of the
external tape drive to eject the cartridge from the drive.
If you encountered any problems during this procedure, see Chapter 7 for
troubleshooting procedures.

To protect your data cartridges and the information on them, observe the
guidelines and avoid the pitfalls in table 7.
Table 7 Cartridge
Guidelines and Pitfalls
42
Guidelines to Follow...
Pitfalls to Avoid
Use DDS cartridges at
temperatures from 5° C (40° F) to
40° C (113° F). Cartridges can be
stored at temperatures down to 40° C (-40° F).
Do not expose cartridges to direct
sunlight, moisture, excessively
dry or humid places, extreme
changes in temperature or
humidity, or X-rays.
Handle cartridges gently.
Do not treat cartridges roughly or
drop them.
Keep cartridges in plastic cases
when they are not in use.
Do not try to clean the tape
guides or tape path inside the
cartridge.
DDS-4/DAT 72 User’s Guide
Chapter 4 Operating Your Tape Drive
Loading a Cartridge
Guidelines to Follow...
Pitfalls to Avoid
Apply just one label to the
designated area on the cartridge.
Affixing more labels can jam the
drive.
Never touch the exposed tape
media with your fingers.
If your data is important,
consider reading data off of tapes
and rewriting to new and
perhaps more modern tapes
every few years.
Never leave cartridges close to
magnetic fields, such as near a
monitor or telephone handset.
If cartridges are exposed to
temperatures or humidities
outside the specified operating
environment, expose them to the
operating environment for a time
equal to the period that the
cartridges were exposed to the
out-of-specification environment
(up to a maximum of 24 hours).
Do not read from or write to
cartridges when a temperature
change of 10° C per hour is
occurring.
Loading a Cartridge
4
Quantum DDS drives have a front-loading cartridge bay for easy
operation. To load a cartridge:
1 Hold the cartridge so the label is facing up and the exposed media is
facing the drive.
2 Gently insert the cartridge into the drive (see figure 13). The drivebay door opens automatically when a cartridge is inserted.
After you insert the cartridge, there is a brief delay while the drive
identifies the cartridge type and state, and moves the tape to the data
area. Then the Media LED turns ON.
DDS-4/DAT 72 User’s Guide
43
Chapter 4 Operating Your Tape Drive
Initializing a Blank Cartridge
Figure 13 Loading a
Cartridge
Initializing a Blank Cartridge
4
When you insert a blank cartridge into the drive for the first time, the
drive takes from 10 to 12 seconds to determine that the tape is blank. The
drive automatically initializes the tape as soon as it receives a SCSI
“Write” command from the host computer. Initializing a blank tape takes
about 30 seconds.
Unloading a Cartridge
4
To unload a cartridge:
1 Be sure the Drive LED is OFF.
Caution:
44
To ensure integrity of your backups and restores, do
not press the Eject button when the Drive LED is ON.
DDS-4/DAT 72 User’s Guide
Chapter 4 Operating Your Tape Drive
Write-Protecting a DDS Cartridge
2 Press the Eject button on the front panel of the drive to unload the
cartridge (see figure 14). The drive automatically flushes the drive
buffer to tape, rewinds the cartridge, updates the system log, and
ejects the cartridge. This may take up to three minutes. Do not powerdown the tape drive or host computer during this time.
Note:
The backup software may issue a command to the drive
that prevents the Eject button from ejecting the tape. If the
tape does not eject, try ejecting it using your backup
software commands.
Figure 14 Eject
Button on Front Panel

Write-Protecting a DDS Cartridge
4
Write-protecting a DDS cartridge protects the data on the cartridge from
being changed, overwritten, or deleted. To write-protect a cartridge, slide
the write-protect tab on the back of the cartridge to the open position (see
DDS-4/DAT 72 User’s Guide
45
Chapter 4 Operating Your Tape Drive
Cleaning the Tape Heads
figure 15). To write-enable the cartridge, slide the write-protect tab so the
hole is closed (see figure 15).
Caution:
Figure 15 Writeprotecting a DDS
Cartridge
Write-protecting a cartridge does not protect the data on
the cartridge from bulk-erasure or degaussing. Do not
bulk erase DDS cartridges; otherwise, you will lose all of
your data on the cartridge and your data will not be
recoverable.

Cleaning the Tape Heads
If excessive dust or debris collects at the tape heads, your drive may not
be able to read from or write to tape. To avoid this situation, clean the
drive’s tape heads:
46
•
After every 50 hours of operation.
•
If the Clean LED goes ON or flashes.
•
If the Media LED flashes when the drive is operating.
DDS-4/DAT 72 User’s Guide

Chapter 4 Operating Your Tape Drive
Cleaning the Tape Heads
To clean tape heads, use a Quantum-qualified DDS cleaning cartridge.
Note:
Do not use an audio DAT cleaning cartridge, as the drive
cannot recognize it. Also, avoid liquids, swabs, and other
methods other than those recommended in this section.
To clean the tape heads:
1 Insert a Quantum-qualified DDS cleaning cartridge into the drive.
The drive loads and runs the cleaning cartridge for about 30 seconds.
Note:
If the cleaning cartridge runs for less than 30 seconds and
the Clean LED is flashing, the cartridge has expired.
Replace the cleaning cartridge with a new one and repeat
step 1.
2 When the cleaning cartridge finishes cleaning the heads, the drive
ejects the cartridge automatically.
3 Remove the cleaning cartridge from the drive and store the cartridge
in a safe place.
Most cleaning cartridges are good for roughly 30 cleaning cycles. When
the cleaning cartridge is used up, the Clean LED will flash rapidly and
the cleaning cartridge should be replaced.
Observe the following guidelines when cleaning tape heads:
•
Each time the cleaning cartridge is loaded, a new, unused portion of
cleaning tape is advanced over the entire tape path. The drive does
not rewind a cleaning cartridge. After about 30 cleaning cycles, the
entire tape is used up and should be replaced. The Clean LED flashes
when the cleaning cartridge needs to be replaced.
•
The DDS-4 and DAT 72 drives have a TapeAlert feature that notifies
your backup software application when the tape heads need to be
cleaned or when a cleaning cartridge needs replacement.

Missing or Damaged Parts
6
If any of the contents included with your DDS-4 or DAT 72 drive are
missing or damaged, contact your place of purchase immediately.
SCSI ID Problems
6
Each SCSI device on the same SCSI bus must have a unique SCSI ID. The
default SCSI ID for internal and external DDS-4 and DAT 72 drives is 6.
You should leave this default SCSI ID unchanged unless another device
on the SCSI bus is already using this ID.
If the default SCSI ID is already in use, you can change the default SCSI
ID on the drive using either jumpers on the back of the internal tape
drives or the SCSI ID Selector switch on the back of the external SCSI
drives. After you set the SCSI ID, record your setting. For more
information about SCSI IDs, see SCSI ID on page 15 if you have an
internal tape drive or an external tape drive.
SCSI Termination Problems
6
If an external DDS-4 or DAT 72 drive is the last device or the only device
in a SCSI chain, you must install a terminating plug on the unused SCSI
connector. For more information, see Checking SCSI Termination on
page 27.
The internal DDS-4 and DAT 72 drives do not provide SCSI termination.
Therefore, do not install these drives as the last devices in the SCSI chain.
If the drive is the only SCSI device, attach the drive to the connector
which is next to last on the SCSI chain and attach a multi-mode
terminator to the last connector in the chain. For more information, see
Checking SCSI Termination on page 27.

The internal DDS-4 and DAT 72 drives are designed to install in most
servers using the hardware accompanying the drives, without requiring
additional items. However, if your server requires additional items to
install the internal DDS-4 or DAT 72 drives, or if any original server
components are damaged or lost, contact your server manufacturer or
vendor.
Drive Does Not Work
6
If the green Power-On LED on the external tape drive does not go ON, or
if the internal tape drive does not work:
1 Check the power connection to the drive.
2 If the connection is secure, replace the power cable with one that is
known to work.
3 If the drive still does not work, contact the Technical Support
department.
Power-On Self-Test Fails
6
If the drive fails its Power-On Self-Test:
1 Check for a cartridge in the drive. If you find one, eject it.
2 Power-down the drive and power it up again.
3 If the drive still fails its Power-On Self-Test, contact Technical
Support.

Computer Does Not Boot
Computer Does Not Boot
6
If the computer does not boot after you install the drive:
1 You may have forgotten to reattach the computer’s power cable,
which you removed when you installed the drive. Be sure all cables
are connected properly to the computer.
2 Be sure the computer’s power cable is connected to a power outlet
that is known to work. Plug into the outlet another appliance, such as
a lamp, that you know to work. If the appliance does not work, the
problem is with the outlet.
3 The power outlet connected to the computer is controlled by a wall
switch that is removing power from the outlet. Either switch outlets
or set the wall switch so that power is applied to the outlet.
4 The computer has two SCSI host adapters installed whose resources
are conflicting with each other. Remove the conflicting device or
consult the documentation that came with the device for suggestions
about resolving the problem.
Computer Does Not Recognize Drive
6
If your computer does not recognize the drive:
1 Verify that the SCSI and power cables to the drive are installed
properly.
2 The drive may be using a SCSI ID assigned to another SCSI device on
the SCSI bus. If so, reassign a unique SCSI ID to the drive or to the
conflicting device.
3 Check that the SCSI bus is terminated properly. Note that the internal
DDS-4 and DAT 72 drives do not provide SCSI termination and,
therefore, should not be the last devices on a SCSI chain.

If your backup application program does not recognize the drive:
1 Use the Windows Device Manager to determine whether the
operating system has recognized the drive. If the tape drive is
recognized properly, it appears under the Tape Drive category. If the
tape drive was recognized, but native drivers are not installed, it
appears under Other Devices. The backup software supplies the
necessary drivers for the tape drive and native drivers are not
required.
2 If the Device Manager shows the drive, check the documentation that
came with your backup program to determine whether the program
needs a particular driver to be installed.
3 If the Device Manager does not list the drive, the drive may not be
installed or configured properly. Check your drive installation and
configuration.

Your DDS-4 or DAT 72 tape drive includes permanently installed,
electrically upgradeable flash memory. This memory allows qualified
OEMs to revise DAT 72 and DDS-4 SCSI firmware quickly and easily. It
also prolongs the life of the tape drive by allowing the drive to inherit
leading technologies as soon as those technologies become available.
This appendix describes how to load firmware onto your tape drive.

You can upgrade your tape drive’s firmware two ways:
•
Using the diagnostic software available at
www.quantum.com/support. This software uploads a firmware file
via SCSI from your host computer to the tape drive.
•
Using Quantum OEM firmware cartridges
DDS-4/DAT 72 User’s Guide

Using Firmware Cartridges
Using Firmware Cartridges
1
The following procedure describes how to upgrade the tape drive
firmware using a firmware upgrade tape cartridge. Firmware upgrade
cartridges are available only to qualified Quantum OEM customers.
Contact your sales representative for information.
Note:
The firmware can also be upgraded from a host computer via
the SCSI connection using software available at
www.quantum.com.
1 Power on the host system with the DDS-4 or DAT 72 drive installed.
2 Close all applications that might try to communicate with the drive
during the firmware upgrade procedure.
3 Insert the firmware upgrade cartridge. The drive automatically
recognizes the firmware upgrade cartridge and begins downloading
the firmware from the cartridge into DRAM. When the firmware has
been downloaded into DRAM, the drive ejects the firmware upgrade
cartridge and the Drive LEDs blink in a progressive pattern. When the
blinking pattern stops, the firmware upgrade operation is complete.
Warning:
Once the firmware upgrade cartridge is inserted into
the drive, no power interruption can occur while the
firmware is loading. Do not power off the drive. If a
power interruption occurs, the firmware may not be
loaded correctly and the drive may not operate
properly.
Do not power down the host system or disconnect
power to the drive until the Drive LEDs stop flashing.
Otherwise, the drive may be rendered inoperative.
4 It may be necessary to reboot the system to ensure that your backup
software application continues to recognize the tape drive.
