All, Finally solved the problem. It was the SCSI Cable. Before trying a different SCSI cable, I transferred the SCSI controller and tape drive to a Windows 2000 machine. I updated the firmware and ran all of its diagnostic tools. Everything ran fine. I even made a few backups with no problem. Remember, this was with the original cable.
I then transferred the SCSI controller and tape drive back to the original Linux machine (with the original cable. Still the same problem. So I asked a friend to borrow his SCSI cable and poof...it worked!
