We are running a Windows NT 4.0 Server and we have backups scheduled to run every night using Seagate Backup Software. They have been working fine up until 2 nights ago. The backups are still pending when I get in the next morning. Anyway, I don't think it is the Tape drive because we just got a new one about 3 months ago. Besides that I cancel the pending job and start it manually and it works. An error message shows up in our Event Viewer in Windows NT and tell me that "The driver detected a controller error on \device\tape0" I have even tried putting a brand new tape in the drive and it still happens.
