Media Information check

During power-on and following a SCSI reset, knowledge of the whereabouts of the cartridge is unavailable. It is not possible to execute commands which assume that this knowledge is available until the drive has recovered from the power-on or reset.

The test checks whether the drive knows if a cartridge is physically present in the drive.

If information about the tape cartridge is not available, the test fails with CHECK CONDITION, a sense key of NOT READY, and additional sense of 3E00 (logical unit has not self-configured yet).

Media Write check

This checks whether the media is write-protected. If it is, CHECK CONDITION is reported with a sense key of DATA PROTECT and additional sense of 2700h (write-protected).
