thanks to all who responded with suggestions. It appears for now that
we have a few tapes that are bad. I put a brand new tape in the drive
and the backup runs without complaint. Kind of strange that 4 tapes
gave problems all at the same time but..I plan to watch carefully over
the weekend and only use new tapes to see if the problem re-appears. If
so it probably is a defective tape drive.
thanks!!
