Installing internal tape drives Mounting the Internal Tape Drive 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. 1. Orient the drive so the front of the drive faces the front of the computer. 2. Insert the drive into the computer’s drive bay. 3. Align the drive’s front panel with the front panel of the computer. 4.
Installing internal tape drives 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. Be sure the SCSI bus is terminated properly.
Installing internal tape drives 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: 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.

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.
Installing external tape drives Reviewing Drive Default Settings TABLE 5. External Tape Drive Default Settings (Continued) Parameter Default Setting See... Media Recognition System checking (DDS-4 drives only) Enabled page 36 Power-On Self-Test diagnostic Enabled page 36 Host operating system Microsoft Windows 98/Me/ XP/NT/2000/2003 Server page 36 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.
Installing external tape drives • Recording 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.
Installing external tape drives 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: • Wide SCSI — either Low Voltage Differential (LVD) or Single-ended (16-bit Wide mode).
Installing external tape drives 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. Figure 12 on page 38 shows two examples of using SCSI termination.
Installing external tape drives Completing Your Installation Completing Your Installation To complete and test your external tape drive installation: 1. Reconnect the power cord to the computer’s power connector. 2. 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. When the drive passes the test, all three front-panel LEDs should be OFF. 3. Turn on the computer.

Cartridge Guidelines and Pitfalls Guidelines to Follow...
Operating Your Tape Drive Loading 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.
Operating Your Tape Drive Unloading 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.
Operating Your Tape Drive Write-Protecting a DDS Cartridge 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).
Operating Your Tape Drive Cleaning 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.
Understanding the Drive LEDs 6 This chapter describes the LEDs on the front panel of the DDS-4 and DAT 72 drives. These LEDs provide information about both normal and error conditions. Topics in this chapter are: • “Front Panel LEDs” on page 46 • “LED Summary” on page 47 • “Clean LED” on page 47 • “Media LED” on page 48 • “Drive LED” on page 48 Front Panel LEDs Figure 16 on page 46 shows an example of the LEDs on the drive front panel of the DDS-4 and DAT 72 drives.
Understanding the Drive LEDs LED Summary LED Summary Table 8 on page 47 summarizes the actions of the front-panel LEDs. TABLE 8. LED Quick Summary LED Color Action Description Clean Green ON (Lit) Cleaning is required. Slow Flashing Internal error rate threshold has been exceeded and cleaning is required. Flashing Cleaning cartridge in the drive has exceeded its useful life. Replace the old cleaning cartridge with a new one. ON (Lit) An inserted cartridge is operating properly.

Media LED LED Status Description ON continuously A DDS cartridge has been inserted and the drive is operating normally. Flashing rapidly Drive could not write the tape correctly (maximum rewrite count exceeded) and the write operation failed. Clean the drive heads using an approved DDS cleaning cartridge.
Troubleshooting 7 This chapter provides suggestions for troubleshooting your drives in the unlikely event you encounter a problem with them.
Troubleshooting 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.
Troubleshooting Power-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.
Troubleshooting Backup Program Does Not Recognize Drive Backup Program Does Not Recognize Drive 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 category. If the tape drive was recognized, but native drivers are not installed, it appears under Other Devices.
