i have a theory to my problem but not 100% certain yet.

i have, today, run a amtapetype on the drive. I suspect this process
overwrote the label on the tape. I suspect this as i did an amlabel on a
tape in a different system ysterday and today did an amtapetype. Guess what
i then did an amtape config show and i got 'not an amanda tape'

in my case i suspect operator error (again!)
