I have a raid 1 array of two new WDC 2 TB drives that fail on the 2nd drive all the time. Disabling NCQ might have helped but it is hard to tell. It was stable for a week, but probably failed 10 times over the weekend. I either need to add a 3rd drive to get any protection from hardware failure, or use lvm to mirror the two drives instead of md :-( /Allan -- Allan Wind Life Integrity, LLC
