Whoa, whoa!  Basic stuff here:  If you get a drive failure, the first thing to
do is physically examine the drive, utilizing the User's Guide for whatever
type of drive it is, as in checking the LCD panel for error indications,
the drive's power state, tape mount/dismount failure, etc.
You perform software commands only as is appropriate to deal with a problem
according to its manifestations.  Running commands at random will at a minimum
waste your time, and can make the problem worse.
