Sense
Key Message Name/Description
0h NO SENSE. Check the Filemark/EOM/ILI bits and the Additional Sense Code/
Additional Sense Code Qualifier bytes.
1h RECOVERED ERROR. This can be caused by rounding of Mode Parameters on a
MODE SELECT, or may report that READ/WRITE error rates are reaching
subsystem specification limits for optimal operation. The device may still be able to
continue to function without any unrecovered errors for a long period of time,
however. No CHECKCONDITION is generated unless the PER bit of Mode Page 01h
is set.
2h NOT READY. The tape medium is not ready for tape operation commands. Tape
medium might not be present in the drive or may be in the process of loading or
calibrating.
