I think this is what the case is when I go to install windows it says unable to access information and I am not even able to partion the HD. I installed windows on an older HD. Windows will recongize the drive in the device manager but it doesn't show up in My Computer. I just don't know what to do and I just bought this HD and don't want to RMA plz how do I fix this because I know corrupted MBR doesn't kill a HD. It is a 40 gig Maxtor DiamondMax Plus 8.
