The problem does sound external to the disks. Someone else suggested the power supply. I wouldn't suspect both cables to have problems, so that's probably not an issue.

Have you looked inside the PS? What you think of a separate cables may be joined at the base in the PS. And then if one cable has a high resistance short, it affects voltage on both legs. And if the output tap feeding those two wires (even separate wires on the same "bus" or "tap" are "joined at the base" electrically speaking) has a problem ... it appears on both wires.

That said, *usually* problems in the wires are "opens" and you just lose that one "leg".

I was actually referring to the SATA cables. I guess my reply got a bit garbled there. One topic at a time... :)

I take your point regarding the power supply cables. I'll put the drives on separate legs and see what happens.
