   Blocksize mismatch maybe ?
   Did you run anything like "mt -f /dev/nst1 defblksize NN" or "setblk
NN" by any chance ?

Last month, one of my three AIT-3 drives (in a 126-Qualstar library)
started showing tape mount filaures.  The following is a sample:

03/10/04 22:34:17 nsrd: media info: loading volume Full.0343 into
/dev/nst1
03/10/04 22:34:35 nsrd: /dev/nst1 Verify label operation in progress
03/10/04 22:35:47 nsrd: media warning: /dev/nst1 reading: Success
03/10/04 22:36:07 nsrd: media warning: /dev/nst1 reading: no tape label
found.
03/10/04 22:36:08 nsrd: /dev/nst1 Eject operation in progress
...
03/10/04 22:36:44 nsrd: Jukebox 'jukebox1' failed: expected volume
'Full.0343' got 'NULL'.

This will show up for all available tapes.
No problem with the other drives.

My first conclusion is simply that the drive is failing.   To complicate
matters, if I power down the Qualstar unit, /dev/nst1 will mount
a tape, once.   Then the above will occur.

Has anyone experienced this sort of problem?
Does anyone have any ideas beyond sticking a fork
in the drive?
