Well, it appears that the drive is trying to seek to an invalid
position on the drive.  Here's a (brief) list of SCSI errors that
I haved around here...

Sense key:

        0H:        No sense        (No error)
        1H:        Recovered error (retried sucessfully)
        2H:        Not ready       (device can not be accessed)
        3H:        Medium error    (Media error)
        4H:        Hardware error  (controller error)
