My factory CD-ROM just quit working all of a sudden. Its an internal Samsung SC140 that came installed in my 1998 HP Pavilion 6630. It will eject and close the disc tray, but it won't recognize any CD. If I put one in it just says "Please insert disk into drive D:". Is it just burnt out, or can I fix it somehow. Should I try to find a driver and reinstall it? Any help is appreciated. Thanks!
