SCSI Bad Sense Key Errors (S$SenseKey):
Number: What it means:
0 NO SENSE.  Indicates that there is no specific sense key information to be reported for this device.
1 RECOVERED ERROR.  Indicates that the last command completed successfully with some recovery action performed by the target.  Not a fatal error.
2 NOT READY.  Indicates that the device addressed cannot be accessed.  Operator intervention may be required to correct this situation.  Probable causes of this error:

Winchester:  Wait spin jumper installed or performing self tests.
Optical:  Cartridge not inserted or START button not pressed.
Tape:  Tape not inserted and loaded.

3 MEDIUM ERROR.  Indicates that the command terminated with a nonrecoverable error condition that was probably caused by a flaw in the medium or an error in the recorded data.  A winchester disk showing this error should be formatted.  A tape can be retried, but the data integrity is probably suspect.  This is a fatal error on the optical disk.
4 HARDWARE ERROR.  Indicates that the device detected a nonrecoverable hardware failure while performing a command or self test.  This could be a device or controller failure.
5 ILLEGAL REQUEST.  Indicates that there was an illegal parameter in the command descriptor block or in the additional parameters supplied as data for some commands.  This could be caused by outdated device firmware or interferance on the SCSI bus.
6 UNIT ATTENTION.  Indicates that the removable medium may have been changed or the target has been reset.
7 DATA PROTECT.  Indicates that a command that reads or writes the medium was attempted on a block that is protected from this operation. Disable the write protection on the tape or cartridge and continue.
