I have a Dell Demension 8300 (Windows XP). I was getting an error that the battery was low. I replaced it and now my DVD drives are not being recognized in either BIOS or in the OS at all. The drives have power and open and close and seem to be spinning but the computer is not recognizing them. I am wondering if this is a problem in BIOS since i replaced the battery, or maybe if the cable needs replacing. The DVD drives worked fine before I replaced the battery. Could this just be coincidence that the cable went bad too? I would appreciate any help with this.
