I have a fully functioning SCSI tape drive (via Linux at the moment) and
want to
image various sorts of Data General (and other) tapes safely and
also duplicate a couple of them. They are in various odd formats. I can
use the non-rewinding device (/dev/nrst0 etc) to get individual files off
the tapes but that is tedious and writing a tape like that seems like a
nightmare.
I found tcopy and built it - but it expects two drives and does not deal
with the
drive-and-file case.

I have some code that I run on Linux to write the contents of a SIMH style
.TAP tape image file to a SCSI tape drive that I've used with Exabyte
EXB-8200 drives. Plus also do the reverse to read the tape back to an image
file for verification, or create an image of a tape.
The code I use was originally based off of the 2.11BSD distribution
maketape code.
I'm sure there a many variations of this sort of code out there. I could
send you the code I use if you're interested.
There is also ST.EXE here for MS-DOS you could look at:
