I'm just repeating what I've seen elsewhere - which is that if you have hot-swaps you can yank a drive and it doesn't show as failed in the raid. I don't have any SATA's myself - mine are all SCSI and they have failed correctly. Perhaps it depends on the failure mode. -- Les Mikesell lesmikesell at gmail.com
