It probably explains the problems you've been having with the raid not 'just recovering' though. I saw this: http://www.linuxquestions.org/questions/linux-kernel-70/sata-issues-568894/ What does smartctl say about your drive? IMO the spare drive is no longer useful for data recovery - you may want to use ddrescue to try and copy this drive to the spare drive. David PS Don't get the ddrescue parameters the wrong way round if you go that route... - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
