What about SMD termination?  Could I be doing something wrong?  The
   M2372K is the second drive in the chain, and it just has ribbon cables
   going in.  I assume that the termination must be internal.  The command
   cables are twisted pair ribbons.  The data cable is just a plain
   ribbon.  That is worrisome... these cables are in an area which must
   have high levels of EM.interference (computers, disk drives and lots of
   other cables)      

	This does sound dicey. SMD command cables are daisy-chained
and terminated on the last drive in the chain with a small resistor
pack designed to fit the two-row connector. If you have a pair of
drives in a rolling rack (for example, the 3/260-sized rack that
houses a pair of 300MB disks) and are plugging in DB cables to the
back of that, the command connector is internally terminated. If you
are plugging into bare drives, you need to supply the termination.

	I'm not exactly sure where you'd find such things, other than
the same junk piles where you'd be likely to turn up SMD drives in the
first place.
