Right. That was other thing that I was going to ask about. Is there a
way to tell the COPY command to not fail on errors? Is there a better
command than COPY to use to move files over?

I checked out the Catweazel recently and it's turned into much more than a
disk controller. That's not a bad thing, but at any rate, is the
software/drivers any good?

Can you provide a few more details? I assume the ZIP drive is running off
a SCSI interface? How do you make the RX02 images under RT11: what
utility do you use?

I'm assuming since I can't find anything about subdirectories on RT11 that
they don't exist?
