http://www.quantum.com/am/service_support/Index.aspx.

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 the ESD instructions that follow 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.

• 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 10

Chapter 2 Installing Internal Tape Drives

Installation Summary

• 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.

• 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.

Installation Summary 2

The following steps summarize the installation procedure for your
internal tape drive.

Collecting the Necessary Tools

Collecting the Necessary Tools 2

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

Reviewing Drive Default Settings 2

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 connectors

• The switches are located on the underside of the drive. If you change
a switch setting, you must turn the power to 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
requirements or need to be changed.

Note: These jumper pin and switch settings are for the SCSI drive

only.

• If you do not need to change these default settings, proceed to

Data Compression

Data Compression 2

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.

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.

Connecting a SCSI Cable

Connecting a SCSI Cable 2

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 Termination 2

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 SCSI Cable

Connecting a SCSI Cable 3

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.

Using the Appropriate Media 4

The Quantum DDS-4 and DAT 72 drives use data-grade DDS cartridges,
which comply with ANSI specifications listed in the “3.81 mm Helical­Scan 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). MRS cartridges have a series of alternate opaque and clear stripes

DDS-4/DAT 72 User’s Guide 46

Chapter 4 Operating Your Tape Drive

cartridge.

Chapter 4 Operating Your Tape Drive

Guidelines to Follow... Pitfalls to Avoid

Loading a 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.

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 17

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.

Initializing a Blank Cartridge

Figure 17 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: To ensure integrity of your backups and restores, do

not press the

Cleaning the Tape Heads

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.

Cleaning the Tape Heads 4

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.

DDS-4/DAT 72 User’s Guide 51

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.

Missing or Damaged Parts

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
internal tape drive or an external tape drive.

SCSI ID on page 16 if you have an

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
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 Problems

Mounting Hardware Problems 6

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 the Technical

Support department.

DDS-4/DAT 72 User’s Guide 60

Chapter 6 Troubleshooting

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. 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 Methods 1

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

DDS-4/DAT 72 User’s Guide 64

http://www.quantum.com/am/service_support/

Appendix A Loading Revised Firmware

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.

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.
