3. Use the correct media type:
• HP LTO-6 Ultrium 6.25 TB RW and LTO-6 Ultrium 6.25 TB WORM cartridges for use with
LTO–6 tape drives.
• HP LTO-5 Ultrium 3 TB RW and HP LTO-5 Ultrium 3 TB WORM tape cartridges for use
with LTO–5 tape drives.
• HP LTO-4 Ultrium 1.6 TB RW* and Ultrium 1.6 TB WORM tape cartridges for use with
LTO–4 tape drives.
4. Has the cartridge been write-protected, see Write protecting cartridges (page 39)?
5. Clean the tape heads with the cleaning cartridge, see Cleaning cartridges (page 36). Make
sure you are using the HP Ultrium Universal cleaning cartridge, C7978A.
6. If the Tape LED is flashing, the cartridge is probably faulty. Try using a different cartridge.
7. Try the operation again.
8. If the problem still occurs and you have not yet replaced the cartridge, try using a different
cartridge.
9. 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, see
table above or 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.
