17
Installing internal tape drivesWhat Else You Need
What Else You Need
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 http://support.certance.com.
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.

Collecting the Necessary Tools
Before proceeding with the installation, gather the tools you will need to install the internal tape
drive into the computer mounting bay. The following list identifies some of the tools you will need.
You may need additional items, depending on your installation requirements.
•Phillips screwdriver
•Flatblade screwdriver, if your computer uses flathead screws
•Torx screwdriver, if your computer uses torx screws
•Computer documentation, which you can refer to during the installation
Reviewing Drive Default Settings
Your internal tape drive comes with various default settings. These settings are configured using
jumpers and switches.
•The jumpers are located on the back of the drive, between the SCSI interface and power con-
nectors (see Figure 3 on page 20)
•The 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 (see Figure 4 on
page 21).
You may need to change these settings to suit your requirements. Review the default settings in
Table 2 on page 20 to determine whether they suit your requirements or need to be changed.
•If you do not need to change these default settings, skip to “Accessing the Inside of Your Com-
puter” on page 26.
•To change one or more settings, refer to the appropriate page in Table 2 on page 20.
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.
TABLE 3. SCSI IDs and Corresponding Jumper Settings
TABLE 3. SCSI IDs and Corresponding Jumper Settings (Continued)
Jumpers
SCSI ID
12OpenOpenShuntedShunted
13ShuntedOpenShuntedShunted
14OpenShuntedShuntedShunted
15ShuntedShuntedShuntedShunted
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).
By default, parity checking is enabled on the internal tape drive. To disable parity checking, remove
the jumper from pins 9 and 10.
1–23–45–67–8
Pins 9-10 open: Disable parity checking
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
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.
Pins 11-12 open: Disable terminator power (default)
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 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.
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.
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
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
your Tape Resource CD and at http://support.certance.com.

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 drivesConnecting 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.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.
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 on page 30 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.

Completing Your Installation
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 24), 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 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.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.
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 43).
If you encountered any problems during this procedure, see Chapter 7 for troubleshooting
procedures.

Installation Summary
The following steps summarize the installation procedure for your external tape drive.
1.Review the Drive’s Default Settings
See “Reviewing Drive Default Settings” on page 34.
2.Record Your Drive’s Information
See “Recording Drive Information” on page 36.
3.Attach a SCSI Interface Cable
See “Connecting a SCSI Cable” on page 37.
4.Terminate the SCSI Bus, if Necessary
See “Checking SCSI Termination” on page 38.
5.Attach a Power Cable
See “Connecting a Power Cable” on page 38.
6.Complete and Verify Your Installation
See “Completing Your Installation” on page 39.
Reviewing Drive Default Settings
Your external tape drive comes with various default settings. You may need to change these settings
to suit your requirements. Review the default settings in Table 5 on page 34 to determine whether
they suit your requirements or need to be changed.
Note: These settings can be changed by accessing the switches located on the bottom of the
drive. Turn the drive over and gently pull the tab on the access door to release it. Once the
door is open, the switches will be accessible. Please refer to pages 20 - 21 for details about
the switch settings.
•If you do not need to change these default settings, skip to “Connecting a SCSI Cable” on
page 37.
•To read about a setting, go to the page referenced in Table 5 on page 34.

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
page 35).
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 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.
35
Installing external tape drivesRecording 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.
36
Installing external tape drivesConnecting a SCSI Cable
Connecting a SCSI Cable
The external tape drives provide two 68-pin, shielded connectors on the back panel (see Figure 11
on page 35). 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 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 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.
Connecting to a Wide SCSI Connector
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 on page 35).
3.If desired, use the other SCSI connector on the back panel of the external tape drive to attach
another SCSI device.If the external tape drive is the last or only device in the SCSI chain, terminate the SCSI chain (see “Checking SCSI Termination” on page 38).
Connecting to a Narrow SCSI Connector
The external tape drives have an Ultra Wide SCSI interface. Obtaining a 50-to-68 pin adapter lets
you connect the 68 pins on the external tape drive to the 50 pins on the computer’s narrow SCSI
bus.
1.Turn off your computer.
2.Connect the adapter to your computer’s 50-pin SCSI connector.
3.Connect the SCSI cable with the adapter to either of the two 68-pin SCSI connectors on the
back of the external tape drive (see Figure 11 on page 35).
4.If desired, use the other SCSI connector on the back panel of the external tape drive to attach
another SCSI device.If the external tape drive is the last or only device in the SCSI chain, terminate the SCSI chain (see “Checking SCSI Termination” on page 38).
NOTE: Be sure the upper 8 data bytes of the 68-pin cable are properly terminated.
Checking SCSI Termination
If the external tape drive is the last or only device in the SCSI chain, install a terminating plug on the
unused SCSI connector on the drive’s back panel. This terminator typically is a small, rectangular
plastic block that is marked SCSI Terminator. Figure 12 on page 38 shows two examples of using
SCSI termination.

•“Unloading a Cartridge” on page 43
•“Write-Protecting a DDS Cartridge” on page 44
•“Cleaning the Tape Heads” on page 45
Using the Appropriate Media
The Seagate DDS-4 and DAT 72 drives use data-grade DDS cartridges, which comply with ANSI
specifications listed in the “3.81 mm Helical-Scan Digital Computer Tape Cartridge for Information
Interchange,” ANSI X3B5/89-156 standard.
For optimum performance and maximum storage capacity, use MRS tape cartridges that correspond
to the format supported by your drive (see Table 6 on page 41). MRS cartridges have a series of
alternate opaque and clear stripes at the beginning of the tape. These stripes classify the media as
data-grade.

Handling Cartridges
To protect your data cartridges and the information on them, observe the guidelines and avoid the
pitfalls in Table 7 on page 41.
TABLE 7. Cartridge Guidelines and Pitfalls
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).
Handle cartridges gently.Do not treat cartridges roughly or drop them.
Keep cartridges in plastic cases when they are not
in use.
!!
!!
!
Do not expose cartridges to direct sunlight, moisture, excessively dry or humid places, extreme
changes in temperature or humidity, or X-rays.
Do not try to clean the tape guides or tape path
inside the cartridge.
Apply just one label to the designated area on the
cartridge. Affixing more labels can jam the drive.
If your data is important, consider reading data off
of tapes and rewriting to new and perhaps more
modern tapes every few years.
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).
Never touch the exposed tape media with your fingers.
Never leave cartridges close to magnetic fields,
such as near a monitor or telephone handset.
Do not read from or write to cartridges when a temperature change of 10° C per hour is occurring.
41
Operating Your Tape DriveLoading a Cartridge
Loading a Cartridge
Seagate 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 on page 42). The drive-bay 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.
FIGURE 13. Loading a Cartridge
Initializing a Blank Cartridge
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.
42
Operating Your Tape DriveUnloading a Cartridge
Unloading a Cartridge
To unload a cartridge:
1.Be sure the Drive LED is OFF.
CAUTION: To ensure integrity of your backups and restores, do not press the Eject button
when the Drive LED is ON.
2.Press the Eject button on the front panel of the drive to unload the cartridge (see Figure 14 on
page 43). 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
power-down 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.

Write-Protecting a DDS Cartridge
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 Figure 15 on page 44). To write-enable the cartridge, slide the write-protect
tab so the hole is closed (see Figure 15 on page 44).
CAUTION: 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.

Operating Your Tape DriveCleaning the Tape Heads
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
cartridge, Model STDMCL, that can be ordered from http://shop.certance.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 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.When the cleaning cartridge finishes cleaning the heads, the drive ejects the cartridge auto-
matically.
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
If any of the contents included with your DDS-4 or DAT 72 drive are missing or damaged, contact
your place of purchase immediately.

TroubleshootingSCSI 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
IDs, see “SCSI ID” on page 21 if you have an internal tape drive or “SCSI ID” on page 35 if you
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
Termination” on page 38.
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 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 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
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.
50
TroubleshootingPower-On Self-Test Fails
Power-On Self-Test Fails
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 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.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
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.

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
Tape Heads” on page 45).
2.Try to run a short backup and verify.
3.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.Press the Eject button to remove the tape.
2.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
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. Topics in this appendix are:
•“Firmware Upgrade Methods” on page 53
•“Using Firmware Cartridges” on page 54
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
http://support.certance.com. This software uploads a firmware file via SCSI from your host
computer to the tape drive.
•Using Seagate OEM firmware cartridges

Loading Revised FirmwareUsing 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
using software available at http://support.certance.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.
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.
