Thanks again for yuour help. The output follows: > What I see are a load of raw read errors plus a smaller number of spin up errors in the statistics table. The diagnosed errors are mostly failures to set a required transfer mode and a failure to queue a read request which is could be a queue overflow due to a failed and retrying read request. I'd replace that disk ASAP. If its less than three years old its under WD guarantee. If you know where you got it the dealer may handle the guarantee claim. Otherwise, contact WD directly. I've had a number of WD 3.5" drives fail, but always after several years use. However, last year I had a string of 2.5" Caviar Blue drives fail after less than 10 hours operation. The first two were replaced through the dealer and failed almost immediately. The third went back direct to WD and seems to be working OK though I haven't used it much. BTW, if you're using any sort of mirroring (RAID 1 or RAID 5 and their equivalents) its a good idea to make sure that the disks in the set are *NOT* all from the same batch and, if you're sufficiently mistrustful, not all from the same manufacturer either though, of course, they should all be the same size.
