Hello! Does anyone know the part numbers/approximate cost of a replacement DVDRW drive for an inspiron 9300? Mine was working fine for a few years now, when all of a sudden the drive light is constantly on and the drive won't read anything. (I have tried to re-seat the drive as well as uninstalling it in XP.) (It's the Sony drive currently.) Or if anyone else has any other ideas, that would be great too, thanks!
