If yes, test both hard drives with "SeaTools for Windows" to check if one of them has failed (it's possible for the BIOS to detect a failed hard drive even though Windows can't) Click "Downloads" on this page: http://www.seagate.com/support/downloads/seatools/ (In case you're wondering, your drive doesn't have to be a Seagate drive in order to test it with SeaTools). If both drives pass the test, don't ignore the possibility that one of the drive bays in the dock may be faulty. Swap the drives over to see if this is true. m 0 l Can't find your answer ? Ask !
