Yeah.  I didn't realize I did that until the machine was all set up and
installed and it seemed easier to leave it that way since nobody could
say why it was a stupid idea.  I have this on the primary master, and a
4 gig drive that seems to be stuck in PIO4 mode as secondary master.  I
wanted to put a DVD-ROM in for direct copying, but until I had to remove
that second harddrive, the case was such that any additional drives
wouldn't fit in their bays because of the motherboard not being small
enough.  Blech, PC crap.

I don't know.  My scsi zip drive works fine.  On the other hand, nothing
I could do would make this system except a SCSI harddrive under linux.

Interesting idea.  I'll look into it.
