Ok, so, this is what's up. (BTW, Anyone posting any "OMGF GOD Windows 7 suxxors MAc OS EX FOREver" posts will get kicked in the nuts and told what a noob bitch they are.) I have an Asus mobo, running Windows 7. I have two Western Digital 640 GB HDD's configured into a Raid 1 (redundant raid). At boot, when the board detects the Raid it tells me that "A disk in the Raid Array has failed." Now, the machine still boots into Windows 7, albeit a little slower than usual (because it's having to check for all the data on two and keep going back to 1 disk to parse the data missing from the first). I've ran Western Digitals utility to check each disk in the system, and each one checks out fine. Apparently this is BS, cos the Mobo obviously is telling me that 1 had failed. My question is, how do I figure out which disk is bad and then how do I replace said disk without having to re-install Windows 7. (I want to avoid having to install all my games and programs). Any help is much appreciated.
