Action
1.
Make sure that the cartridge is not a WORM cartridge that has already been used.
2.
Make sure that the cartridge is write enabled (move the write-protect switch to the enabled position).
3.
Make sure that the data cartridge is compatible with the drive model. LTO tape drives can read data
cartridges from two generations back and write to data cartridges one generation back. See Data
cartridges on page 16.
4.
Make sure that you are using an Ultrium cartridge that has not been degaussed. Do not degauss
Ultrium cartridges!
5.
Verify that the cartridge has not been exposed to harsh environmental or electrical conditions.
6.
Inspect the cartridge for physical damage.
7.
Many backup applications do not read or write to cartridges that were created using a different
backup application. In this case, you may have to perform an erase, format, or label operation on the
cartridge.
8.
Review any data protection or overwrite protection schemes that your backup application may be
using. The application could prevent the tape drive from writing to a given cartridge.
9.
Retry the operation with a different, known good cartridge.
10. Clean the tape drive from the Operation > Clean Drive screen.
