OK.  Stranger by the minute.  I removed the first tape (01) and set it
up to use the second tape(02).  I issued a "amcheck fea" and it said my
second tape was OK and that I should be able to backup.  I then issued
an amflush and it came back with an error.  I then rewind the tape with
"mt rewind", turn around and issue another amcheck fea, and the tape has
an error on it.  So, the amflush and/or amdump process is writing
something to the tape that causes it to not be usable after that point.

Is this sounding like a scsi error or some type ?
