Page 22: Parity Checking
TABLE 3. SCSI IDs and Corresponding Jumper Settings (Continued) SCSI ID 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). -
Page 23: Data Compression
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. -
Page 24: Power-On Self-Test
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). -

Page 26: Accessing The Inside Of Your Computer
Accessing the Inside of Your Computer To gain access to the inside of your computer: Shut down the computer as you would normally. Then turn off the computer and all peripherals connected to it. Remove the computer’s power cord from the computer’s AC connector. Remove the computer cover to gain access to the inside of the computer. -
Page 27: Figure 5. Mounting An Internal Tape Drive
Secure the drive in the mounting bay using two M3.0 metric screws on each side of the drive (see Figure 5 on page 27). As Figure 6 on page 27 shows, the 3.5-inch drive has four screw holes on the bottom and five on each side. WARNING: Do not use screws longer than 4 mm;... -
Page 28: Mounting The Drive Into A 5.25-Inch Drive Bay
Mounting the Drive into a 5.25-inch Drive Bay The following procedure describes how to mount the drive in a 5.25-inch drive bay. This procedure assumes your drive has mounting brackets on the sides. Orient the drive so the front of the drive faces the front of the computer. Insert the drive into the computer’s drive bay. -
Page 29: 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. -
Page 30: Checking Scsi Termination
Checking SCSI Termination 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: Attach it to the next-to-last connector on the SCSI chain. -
Page 31: Completing Your Installation
Power Connector on the Internal Tape Drive FIGURE 10. Completing Your Installation To complete and test your internal tape drive installation: Use the screws you removed earlier to secure the drive in place. Replace the computer cover. Reconnect the power cord to the computer’s power connector. Turn on the computer. -
Page 32: Registering Your Tape Drive
Registering Your Tape Drive After you install the internal tape drive, be sure to register it. Registering your drive ensures that you will receive the latest information about your drive, as well as other product, service, and support information. For your convenience, you can register your drive either through our Web site or by fax. -

Your external tape drive is shipped with a default SCSI ID of 6. -
Page 36: Media Recognition System (Dds-4 Drives Only)
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. -
Page 37: Connecting 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: •... -
Page 38: Checking Scsi Termination
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. -
Page 39: Completing Your Installation
Completing Your Installation To complete and test your external tape drive installation: Reconnect the power cord to the computer’s power connector. Use the On/Off Switch on the back of the external tape drive to turn on the drive (see Figure 11 on page 35). The external tape drive performs its Power-On Self-Test for about five seconds. -

Page 42: Loading A Cartridge
Loading a Cartridge Seagate DDS drives have a front-loading cartridge bay for easy operation. To load a cartridge: Hold the cartridge so the label is facing up and the exposed media is facing the drive. Gently insert the cartridge into the drive (see Figure 13 on page 42). The drive-bay door opens automatically when a cartridge is inserted. -
Page 43: Unloading A Cartridge
Unloading a Cartridge To unload a cartridge: 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. Press the Eject button on the front panel of the drive to unload the cartridge (see Figure 14 on page 43). -
Page 44: Write-Protecting A Dds Cartridge
Write-Protecting a DDS Cartridge Write-protecting a DDS cartridge protects the data on the cartridge from being changed, overwrit- ten, 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). -

Page 50: 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. -
Page 51: Power-On Self-Test Fails
Power-On Self-Test Fails If the drive fails its Power-On Self-Test: 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: You may have forgotten to reattach the computer’s power cable, which you removed when... -
Page 52: Backup Program Does Not Recognize Drive
Backup Program Does Not Recognize Drive If your backup application program does not recognize the drive: 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. -
Page 53: Appendix A - Loading Revised Firmware
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 technol- ogies as soon as those technologies become available. -
Page 54: 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 using software available at http://support.certance.com. -
