Consulting the SCSI2 standard, the drive has signaled a medium error further
specifying that the medium format is corrupted:
Sense key: 03h
Table 69 - Sense key (0h-7h) descriptions
+========-====================================================================+
| 3h | MEDIUM ERROR. Indicates that the command terminated with a non- |
| | recovered error condition that was probably caused by a flaw in |
| | the medium or an error in the recorded data. This sense key may |
| | also be returned if the target is unable to distinguish between a |
| | flaw in the medium and a specific hardware failure (sense key 4h).|
+========-====================================================================+
ASC: 31h ASCQ: 00h
Table D.1 - ASC and ASCQ assignments
+=============================================================================+
| ASC ASCQ DTLPWRSOMC DESCRIPTION |
| --- ---- ----------------------------------------------------- |
| 31 00 DT W O MEDIUM FORMAT CORRUPTED |
+=============================================================================+
It is perfectly valid for the driver to remember this until it is informed
that the tape has changed (unit attention). I hope that helps...
