I had something very similar to this happen with my AIT-2 changer when it had
to be reset to company defaults.  Unbeknownst to me, the default tape for the
changer (drive? I don't remember) was DLT -- and, when it didn't find AIT-2
tapes, it complained bitterly, but not with any error that was obvious.  If
you've done anything "interesting" to your changer/drive lately, you just
might want to make sure it's still configured correctly.
