Have you tried setting up an "AT" command to run a scheduled backup for about a week? Just have you or the users remove the tape each day and make sure in your "AT" command you included the switch to create a backup log. If this runs fine that I doubt it is a hardware issue. Also you can download the Seagate Tape drive Diag for NT. Follow the instructions and run a few test backups in DOS outside of NT. THis will let you know if it is an NT issue :-)
Good luck.
P.S. I have had the same issues so I know.
