How can I get my Hard Drive Bios Setting to Enable in the Bios Settings? I cannot get it to change. I try to hit the plus sign but it does not change it to enable. I am running two hard drives the old one is too small but is running windows Vista, but when I am in Vista it does dot regognize there is another drive attached. Any help would be wonderful and greatly appreaciated.

always post your entire system specs when asking for advice.

what type of drive is it?
if any type of modern SATA drive it should function as plug-n-play.
while Vista is running, plug the drive in to a known functioning SATA port and see if it pops up.
