Jumper Settings
Each SCSI device on the bus must have its own unique ID. Your internal
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 jumper pins 1–2, 3–4, 5–6, and
7–8 to change the drive’s SCSI ID. Table 3 lists the SCSI IDs and their
corresponding jumper settings.

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).
By default, parity checking is enabled on the internal tape drive. To
disable parity checking, remove the jumper from pins 9 and 10.
Note:If you disable parity checking, the drive still generates a parity
bit.

Terminator Power
Terminator Power 2
Jumper Pins 11–12:
Pins 11-12 sh un te d: Ena bl e 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: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.
DDS-4/DAT 72 User’s Guide18
Chapter 2 Installing Internal Tape Drives
Data Compression
Data Compression2
Settings:
Switch 1 ON = Enable hardware data compression (default)
Switch 1 OFF = Disable hardware data compression
Switch 2 ON = Recognize SCSI data compression commands (default)
Switch 2 OFF = 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.
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.
• 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.

Chapter 2 Installing Internal Tape Drives
Media Recognition System (DDS-4 Drives Only)
Media Recognition System (DDS-4 Drives Only)2
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 3 is reserved on internal DAT 72 drives.
Power-On Self-Test 2
Settings:
Switch 4 ON = Drive performs Power-On Self-Test (default)
Switch 4 OFF = Drive does not perform Power-On Self-Test
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.

Host Operating System
Host Operating System 2
Switches: 5, 6, 7, 8
Default Setting: Microsoft Windows 98/Me/XP/NT/2000/2003 Server
Switches 5 through 8 configure the internal tape drive for a host
operating system. By default, these switches are all ON. This setting
configures the drive for a Microsoft Windows 98/Me/XP/NT/2000/
2003 Server operating system.
To use the internal tape drive with a different operating system:
• Set switches 5 through 8 to select the appropriate settings.

Connecting a SCSI Cable
Connecting a SCSI Cable2
The internal SCSI tape drives can be used with a Wide SCSI interface,
either Low Voltage Differential (LVD) or Single-ended (16-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 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.

Checking SCSI Termination2
The internal tape drive does not provide SCSI termination. 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.

Connecting a Power Cable to the SCSI Tape Drive2
To connect a power cable to the internal SCSI tape drive, connect a spare
4-pin power cable from the computer’s internal power supply to the
power connector on the back of the internal SCSI tape drive. Figure 10
shows the location of the power connector on the internal SCSI tape
drive.
The recommended 4-pin power connector for the internal SCSI drives is
an AMP 1-48024-0 housing, with AMP 60617-1 pins or equivalent.

SCSI ID3
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.

Parity Checking3
By default, parity checking is enabled on the external tape drive. If you
disable parity checking, the drive still generates a parity bit.
Data Compression3
By default, data compression is enabled. With this setting, the external
tape 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.
• 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.
DDS-4/DAT 72 User’s Guide39
Chapter 3 Installing External Tape Drives
Media Recognition System (DDS-4 Drives Only)
Media Recognition System (DDS-4 Drives Only)3
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 external tape drive provides a mediarecognition system (MRS) feature that determines whether tape
cartridges conform to the DDS tape standard.
By default, MRS is enabled. With this setting, the drive:
• Reads from and writes to MRS media.
• Reads from but does not write to non-MRS media.
If you disable MRS, the drive reads from and writes to MRS and nonMRS media.
Power-On Self-Test3
By default, the external tape drive responds to SCSI commands only after
it successfully completes the Power-On Self-Test (about 5 seconds). If you
do not want the drive to perform this diagnostic when it powers-up,
disable the Power-On Self-Test.
Host Operating System3
By default, the external tape drive is configured for a Microsoft Windows
98/Me/XP/NT/2000/2003 Server operating system.

After you review and, if necessary, change the drive’s default settings,
record the information.

Connecting a SCSI Cable3
The external tape drives provide two 68-pin, shielded connectors on the
back panel (see
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
figure 15). You can use either connector to attach the drive
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.

Cleaning the Tape Heads4
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

• If the Clean LED goes ON or flashes.
• If the Media LED flashes when the drive is operating.
DDS-4/DAT 72 User’s Guide51
Chapter 4 Operating Your Tape Drive
Cleaning the Tape Heads
To clean tape heads, use a Quantum-qualified DDS cleaning cartridge.
Quantum offers a cleaning cartridge, Model CDMCL, that can be ordered
from
http://www.quantum.com.
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.

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 Termination Problems6
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
page 30.
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 30.

Mounting Hardware Problems6
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 Work6
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 Fails6
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 the Technical
Support department.

Computer Does Not Boot6
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 Drive6
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. If using an HBA for SATA, insure that the driver
for the HBA is installed.
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.

Appendix A
ALoading Revised
Firmware
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 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.
Topics in this appendix are:
• Firmware Upgrade Methods
• Using Firmware Cartridges
Firmware Upgrade Methods1
You can upgrade your tape drive’s firmware two ways:
• Using the diagnostic software provided on your Quantum Resource
CD or available at
Index.aspx. This software uploads a firmware file via SCSI from your
host computer to the tape drive.
• Using Quantum OEM firmware cartridges

Using Firmware Cartridges
Using Firmware Cartridges1
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.
http://
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.
