I've used the Linux scsitape utility (I think it's part of the mtx
package, but can't say offhand). It uses the generic SCSI interface
(/dev/sgxx) rather than the mt driver. Also, even if you use the dd
commands, be sure to install the mt-st package, as it has a bunch of
SCSI tape support logic in it that the default distro doesn't have.

Then I'd
image the tape with Tapeimgr and see if I could figure out
what software was used. I've reverse-engineered a few, Retrospect and
one other, I think I uploaded it all to my Github.
Phil's overall process is good, but you shouldn't use `dd` to image
tapes. It discards tape block length information, which is Bad <tm>.
This Tapeimgr tool just uses dd under the covers. (In some scenarios,
it _may_ be true that the tape blocks are all fixed length, but you may
only get one pass through the tape, so why risk it?)
