If you get an error, it will go into an endless loop creating -1 byte records.

And that is precisely why I'm thinking of an
ad-hoc interface rather
than just plugging a SCSI drive into a UNIX box.
It's eminently possible to image tapes sanely on a unix box. See e.g.:
http://www.brouhaha.com/~eric/software/tapeutils/
The main limitation seems to be that it's hard to get the (broken) data
from a block that had a read error when using SCSI hardware. There's
probably a way around this if one digs into lower layers of SCSI magic;
I haven't gone looking.
