The SCT says the drives will wait at most 7 seconds before returning a problem, so that's what you want (My Barracudas can't do that - a problem waiting to happen). I'll let someone who knows more comment on the rest of the output, but that SCT stuff tells us your problem is not the usual one of someone using the wrong drives. Cheers, Wol
