The termination power is coming from the drive in both cases, and I
actually did try a different cable on the narrow side (a shorter one).
The shorter narrow cable seemed to make the problem occur less often,
but the system still locks up within a few uses of the wide drive.  I
don't have another wide cable, but the one I have is supposed to be a
good one (although it's a bit long).

I was wondering if putting all the drives on the wide cable via
(non-terminating) adapters, leaving the wide drive to terminate the
end, might help, since it would eliminate the narrow cable altogether,
and shorten the bus.

Thanks again.
