Avoiding Electrostatic Damage
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 work-
ing 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 dis-
charge any static electricity buildup from your body.
•
•
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 dam-
age.

NOTES: You can also change SCSI IDs by connecting a SCSI address-selection 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
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: If you disable parity checking, the drive still generates a parity bit.
Terminator Power
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: 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.

Installing internal tape drives
Reviewing Drive Default Settings
Data Compression
Settings:
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.
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 hard-
ware 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.
Media Recognition System (DDS-4 Drives Only)
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 media-recognition 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.

Reviewing Drive Default Settings
Power-On Self-Test
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 pow-
ered 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
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.
Refer to the operating system drive configuration supplement for information on scripts and
other settings for various non-Windows operating systems. This supplement is available on

SCSI Wide/Narrow Configuration (DDS-4 Drives Only)
Settings:
Switch 9 ON = SCSI Wide Operating Mode (default)
Switch 9 OFF = SCSI Narrow Operating Mode
Switch 9 enables SCSI Wide or Narrow operation. By default, switch 9 is set to ON, enabling SCSI
Wide (16-bit) operation. To enable SCSI Narrow (8-bit) operation, set switch 9 to the OFF position.
This allows the DDS-4 drive to terminate the upper byte of the SCSI bus.
NOTE: Narrow SCSI is not recommended.
Switch 9 is reserved on internal DAT 72 drives.
Vendor ID
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 Seagate DDS tape drives.
Recording Drive Information
After you review and, if necessary, change the drive’s default settings, record the drive information.
That way, you can reference this information in the future, without having to gain access to the drive
inside your computer.

Installing internal tape drives
Connecting a SCSI Cable
Connecting a SCSI Cable
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 Single-ended (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 8-bit 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.
Connecting to a Wide SCSI Connector
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 (see Figure 8 on page 29).
FIGURE 8. SCSI Interface Connector on the Internal Tape Drive
Connecting to a Narrow SCSI Connector
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.
2.
Connect the adapter to your computer’s 50-pin SCSI connector.
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
The internal tape drives do not provide SCSI termination. For this reason, they should not be the last
drives.
If the drive is the only SCSI device on the bus:
1.
2.
Attach it to the next-to-last connector on the SCSI chain.
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.

should describe this procedure.
Gently insert a tape cartridge into the internal tape drive’s slot (see “Loading a Cartridge” on
page 42). 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.
8.
Use your backup software application to perform a sample backup-and-verify operation. The
amber Drive LED goes ON as data is written to and/or read from the tape.
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 43).

SCSI ID
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 (see Figure 11 on
NOTES: 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.
FIGURE 11. Back Panel of the External Tape Drive
Parity Checking
By default, parity checking is enabled on the external tape drive. If you disable parity checking, the
drive still generates a parity bit.
Data Compression
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 compres-
sion 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.

Installing external tape drives
Recording Drive Information
•
Data with little redundancy, such as executable programs, are compressed the least.
Media Recognition System (DDS-4 Drives Only)
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 media-recognition 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 non-MRS media.
NOTE: MRS is not available with external DAT 72 drives.
Power-On Self-Test
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 System
By default, the external tape drive is configured for a Microsoft Windows 98/Me/XP/NT/2000/
2003 Server operating system.
Recording Drive Information
After you review and, if necessary, change the drive’s default settings, record the information.

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:
•
•
•
After every 50 hours of operation.
If the Clean LED goes ON or flashes.
If the Media LED flashes when the drive is operating.
To clean tape heads, use a Seagate-qualified DDS cleaning cartridge. Certance offers a cleaning
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 Seagate-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.
3.
When the cleaning cartridge finishes cleaning the heads, the drive ejects the cartridge auto-
matically.
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.

ing on the drive, the Power-On Self-Test switch (switch 4) is enabled and
a Power-On Self-Test has failed. If the front panel LEDs are flashing
together, contact the Technical Support department.
If the Drive LED is flashing rapidly during drive operation, press the
Eject button to remove the tape. If the tape does not eject within 2 min-
utes, press and hold the Eject button for more than 5 seconds. The tape
should eject within 40 seconds. Contact Technical Support for more
information.
NOTE: If your backup software issues a SCSI “Prevent Media Removal” command,
the Drive LED remains ON and the Eject button is disabled, so that the tape cannot
be ejected accidentally. To eject the tape, use your backup software’s Eject
command.

Troubleshooting
SCSI ID Problems
SCSI ID Problems
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
have an external tape drive.
SCSI Termination Problems
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
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
Mounting Hardware Problems
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 addi-
tional 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
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.
2.
3.
Check the power connection to the drive.
If the connection is secure, replace the power cable with one that is known to work.
If the drive still does not work, contact the Technical Support department.

Troubleshooting
Power-On Self-Test Fails
Power-On Self-Test Fails
If the drive fails its Power-On Self-Test:
1.
2.
3.
Check for a cartridge in the drive. If you find one, eject it.
Power-down the drive and power it up again.
If the drive still fails its Power-On Self-Test, contact the Technical Support department.
Computer Does Not Boot
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.
4.
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.
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
If your computer does not recognize the drive:
1.
2.
Verify that the SCSI and power cables to the drive are installed properly.
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.

Troubleshooting
Backup Program Does Not Recognize Drive
Backup Program Does Not
Recognize Drive
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.
•
•
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.
If the Device Manager does not list the drive, the drive may not be installed or configured
properly. Check your drive installation and configuration.
Write Error
If the Media LED is flashing, a write error has occurred.
1.
Use a Seagate-qualified DDS cleaning cartridge to clean the tape heads (see “Cleaning the
2.
3.
Try to run a short backup and verify.
If the Media LED continues to flash, contact the Technical Support department.
Hardware Error
If the Drive LED is flashing rapidly, a hardware error has occurred. If the fault occurs immediately
after powering on the drive, the Power-On Self Test switch (switch 4) is enabled and a Power-On
Self-Test has failed. If the front panel LEDs are flashing together, contact the Technical Support
department.
If the Drive LED is flashing rapidly during drive operation:
1.
2.
Press the Eject button to remove the tape.
If the tape does not eject within 2 minutes, press and hold the Eject button for more than 5 sec-
onds. The tape should eject within 40 seconds.
3.
Contact Technical Support for more information.

Loading Revised Firmware
A
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 technol-
ogies 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
You can upgrade your tape drive’s firmware two ways:
•
Using the diagnostic software provided on your Tape Resource CD or available at
computer to the tape drive.
•
Using Seagate OEM firmware cartridges

Loading Revised Firmware
Using Firmware Cartridges
Using Firmware Cartridges
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 Seagate OEM
customers. Contact your sales representative for information.
NOTE: The firmware can also be upgraded from a host computer via the SCSI connection
1.
2.
Power on the host system with the DDS-4 or DAT 72 drive installed.
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.
WARNINGS: 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 con-
tinues to recognize the tape drive.
