That will give me a more definitive answer. 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. The controller is on the MB and I REALLY don't want to have to tear the machine apart to replace it. The errors have stopped for now. No more errors in the past four hours. At the moment all I can do is keep monitoring it. -- Bowie
