3. Use the correct media type, for example: • DAT 320 media with DAT 320 drives. • DAT 160 media with DAT 160 drives. • DAT 72 media with DAT 72 drives. • DDS-4 media with DAT 40 drives. NOTE: When using the NT backup application with HP StorageWorks DAT 160 or DAT 320 tape drives, the user must choose 4 mm even when using 8 mm tape cartridges. Remember that although tape drives may be able to read earlier-format media, see Table 5 on page 46, the media itself is not backward-compatible • DAT 320 media will be ejected by all drives other than DAT 320 drives • DAT 160 media will be ejected by all drives other than DAT 320 and DAT 160 drives • DAT 72 media will be ejected by DAT 320 and DAT 40 drives. • DDS-4 media will be ejected by DAT 320 and DAT 160 drives. 4. Has the cartridge been write-protected, see "Write-protecting cartridges" on page 48? 5. Clean the tape heads with the cleaning cartridge, see "Cleaning cartridges" on page 49. Be sure to use the correct cleaning cartridge. • DAT 320 cleaning cartridges (Q2039A) with DAT 320 tape drives. • DAT 160 cleaning cartridges (C8015A) with DAT 160 tape drives. • Standard cleaning cartridges (C5709A) with all other HP StorageWorks DAT tape drives 6. Try the operation again. 7. If the problem still occurs, try using a different cartridge. 8. If the problem is still there, the problem probably lies with the drive or the host computer. Has the drive been moved recently? Have any cables been disconnected and reconnected? Has the environment changed-unusually hot, cold, damp or dry? Has there been dust or dirt near the drive. Have reasonable precautions against static been taken? The problem could lie with the drive: 1. Check the cables and connectors. 2. Clean the tape heads with the cleaning cartridge. 3. If the problem persists, check the environmental conditions against the specified limits (refer to http://www.hp.com). Perhaps move the drive to a more suitable site. Has a new operating system been installed in the host computer? Has new backup software been installed? The problem could lie with the host or the software. Consult the computer's operating manuals, the software manual, or seek help from a service engineer. Certain backup applications require you to use their own Tape driver instead of the HP Tape driver. 62 Troubleshooting
