Unloading a Tape Cartridge
1. Ensure the tape drive is not selected from the host.
2. Press the Unload switch.

Reclaiming (Reformat) a Tape Cartridge
When a tape cartridge is corrupted or formatted for special uses such as dump or
firmware, it can be reformatted as a data tape and returned to normal usage. This
procedure is referred to as reclaiming a tape for normal use.
1. Take the tape drive offline.
2. Press Menu until the Drive Mode Main Menu is reached. “Drv Menu?” displays.
3. Press Select to enter the Drive Menu.
4. Press Menu until “MakeDataTp” appears.
5. Press Select to initiate; any tape cartridge present in the drive is ejected.
6. When the “Ld Data Tp” displays, place a write-enabled tape in the drive. The
operation starts automatically and erases and reformats any tape.
If “DatCrFailx” is displayed (where x = 1), see Table A-2 in Appendix A for
instructions on how to handle this error condition.
7. When done, exit Drive Mode and remove the tape from the drive.
8. Put the drive online.
