I have two SCSI tape trives, one on each of two computers. One is about
three years old and gets problems only when a tape gets about three years
old (running two passes or so per week), or when I put an incompatible
tape in the drive (A VXA-2 tape in a VXA-1 drive: the tapes are the same,
but a VXA-1 drive cannot read a tape formatted for VXA-2, and knows it,
and turns on error lights).
The other drive started its useful life in about May 2004 and has never
had a problem as you describe.
If you get the Door Open problem solved (possibly a defective microswitch,
or the link between the door and the microswitch), it may be you are
putting a bad tape in. Try putting a factory fresh tape in.
