I've also seen stuff that implies (with spinning rust) that the retry cycle can hang - a read times out, then the next attempt to read the same data works fine. It's *possible* the same applies to SSDs, in which case shortening the timeout could be worthwhile. And as Phil says, the critical fact is that the drive MUST come back from la-la-land BEFORE the kernel times out. Cheers, Wol
