General procedure
If a problem occurs, the first step is to try to establish whether the problem lies with the cartridge, the drive, the host computer
and connections, or the way the system is being operated.
Has the system just been installed?
There could be an installation problem:
1.
Check through the information in the relevant installation chapter of this guide.
2.
Check the power connectors and SCSI cabling.
3.
Is the SCSI ID correctly set? Is there a SCSI system conflict? Has the SCSI bus been correctly terminated? See "Check
the internal drive's SCSI ID" on page 15 and"Check the external drive's SCSI ID" on page 23.
4.
Are appropriate drivers and application software installed on the host?
5.
Check the environmental conditions against the specified limits.

Operating
Storage
Are you using new cartridges or a different brand of cartridge? Have you been using the particular cartridge for a very
long time?
The problem could lie with the cartridge:
1.
Check through the media chapter, "Use the correct media" on page 35.
2.
Check that you are using an Ultrium cartridge. Compatible media can be recognized by the LTO logo, which is the same
as the logo on the front of your drive.
3.
Use the correct media type, for example:
• Ultrium 1.6 TB RW and Ultrium 1.6 TB WORM tape cartridges for use with LTO–4 tape drives.
• Ultrium 800 GB RW and Ultrium 800 GB WORM tape cartridges for use with LTO–3 tape drives.
• Ultrium 400 GB RW tape cartridges for use with LTO–2 tape drives.
4.
Has the cartridge been write protected? See "Write protecting cartridges" on page 36.
5.
Clean the tape heads with the cleaning cartridge, see "Cleaning cartridges" on page 35. Make sure you are using the
Ultrium Universal Cleaning Cartridge.
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.
