This is the sort of SCSI problem that I absolutely *hate*!!!

Since I couldn't be sure from your post, you *do* have a terminated drive
plugged into the very last plug on the cable don't you?  You just moved the
other internal drive between the two other plugs?

If that's not the case I would feel very nervous about the long-term
stability of your fix, although the distance between those two plugs is
pretty short.  My experience is that you can get things to work by breaking
the rules sometimes, but if you do then the fix may not hold as humidity,
age, whatever change.  In this case the rule is: both *ends* of the chain
must be terminated.

I have seen internal plug terminaters at Fry's sometimes.  If you are
running with the last plug empty I would suggest you get one, put it in the
last plug, and disable termation on the relevant internal drive.

I know this has been an ongoing thread.  Appologies if I duplicated other
postings.
