Data compression (DC) SCSI DC control Media recognition Self Test Wide/Narrow SCSI Inquiry String support Default settings shown Front of drive Internal Tape Drive Switch Settings FIGURE 4. SCSI ID Jumper Pins: 1–2, 3–4, 5–6, 7–8 Default Setting: SCSI ID 6 Each SCSI device on the bus must have its own unique ID.
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).
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.
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).
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.
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;...
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.
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.
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.
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.
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.
Installing external tape drives This chapter describes how to install external DDS-4 and DAT 72 drives. Topics in this chapter are: “Unpacking” on page 33 • “What Else You Need” on page 33 • “Installation Summary” on page 34 • “Registering Your Tape Drive”...

Installation Summary The following steps summarize the installation procedure for your external tape drive. Review the Drive’s Default Settings See “Reviewing Drive Default Settings”...
TABLE 5. External Tape Drive Default Settings (Continued) Parameter Media Recognition System checking (DDS-4 drives only) Power-On Self-Test diagnostic Host operating system 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.
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.
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: •...
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.
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.
Operating Your Tape Drive This chapter describes how to operate your tape drive. Topics in this chapter are: “Using the Appropriate Media” on page 40 • “Handling Cartridges” on page 41 • “Loading a Cartridge” on page 42 • “Unloading a Cartridge” on page 43 •...
TABLE 6. Matching Drives with the Media They Support Media DDS-2 DDS-3 DDS-4 DDS 5 Generation 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.
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.
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).
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).
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. •...
Understanding the Drive LEDs This chapter describes the LEDs on the front panel of the DDS-4 and DAT 72 drives. These LEDs pro- vide information about both normal and error conditions. Topics in this chapter are: “Front Panel LEDs” on page 46 •...

Media LED The Media LED indicates whether a DDS cartridge is operating normally. TABLE 10. Media LED LED Status ON continuously Flashing rapidly As routine maintenance, clean the drive heads after every 50 hours of NOTE: operation. Drive LED The amber Drive LED lets you know when data is being read from or written to tape. It also informs you when a hardware fault occurs.
Troubleshooting This chapter provides suggestions for troubleshooting your drives in the unlikely event you encounter a problem with them. Topics in this chapter are: “Missing or Damaged Parts” on page 49 • “SCSI ID Problems” on page 50 • “SCSI Termination Problems” on page 50 •...
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.
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...
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.
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.
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.
