I just installed my A7N8X and now my external USB 2.0 drive no longer works. It is recognized but I cant access it. I can't even format it. It worked fine on my EPOX board even though that board wasnt usb 2.0 compatible. I've tried every USB port on the A7N8X with no luck. I think XP should automatically operate it at USB 2.0 (I may be wrong) but maybe there is some issue that Im not aware of. Any help would be great.
