4. Verify that another cartridge is not already loaded in the drive. Press the eject
button, if needed.
The Host System Backup Application is Reporting an Error
The host system backup application may report an error as a result of a failure by
the tape drive to write or read data. If your backup application reports a media
error, do the following:
1. Clean the drive (see “Cleaning the Tape Drive” on page 91).
2. Verify that the data cartridge you are using for your backup job is a good one.
Note: The Drive SELF-TEST Procedure can also be used to check the integrity
of your media.
3. Try using another LTO data cartridge for your backup job. Mark any cartridge
that fails. If you notice that the same cartridge is involved in multiple failures,
it may be time to replace that cartridge. In some cases, media suppliers will
replace a defective cartridge at no cost.
4. If you are trying to backup (write) data, verify that your cartridge is not
write-protected. Check the red write-protect switch on the edge of the cartridge,
and confirm that it is in the unlocked position (see “Setting the Write-Protect
Switch” on page 95).
