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.
1 Gather the Necessary Tools (see Collecting the Necessary Tools 2 Review the Drive’s Default Settings 3 Record Your Drive’s Information 4 Access the Inside of the Computer 5 Mount the Drive into the Computer Mounting Bay 6 Attach a SCSI Interface Cable 7 Attach a Power Cable 8 Complete and Verify Your Installation

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 installation

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

If you change the drive’s default SCSI ID, avoid using SCSI IDs 0 and 1 (which typically are assigned to a boot drive) and SCSI ID 7 (which typically is assigned to SCSI controllers or host bus adapters).
Parity Checking 2
Jumper Pins 9–10: Pins 9-10 shunted: Enable parity checking (default) Pins 9-10 open: Disable parity checking
By default, parity checking is enabled on the internal tape drive. To disable parity checking, remove the jumper from pins 9 and 10.
Note: If you disable parity checking, the drive still generates a parity
bit.

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.

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.

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.

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.

Connecting to a Wide SCSI Connector

Checking SCSI Termination

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.

Do not try to clean the tape guides or tape path inside the 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

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.

Chapter 6 Troubleshooting

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.

Backup Program Does Not Recognize Drive

Backup Program Does Not Recognize Drive 6
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 was recognized, but native drivers are not installed, it appears under necessary drivers for the tape drive and native drivers are not required.
2 If the Device Manager shows the drive, check the documentation that
came with your backup program to determine whether the program needs a particular driver to be installed.

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

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.
