I'm having trouble with my dvd rw drive. It won't read any dvd's, cd's, or blank discs that i've put in. It won't even register that there is a disc inside. Yet the hardware manager has no problems picking it up. Make: Phillips (sub cont. Benq Corp) Model: DVD8631/95 ; 930504666395 (E-H900-04-1956) Not sure of the model exactly but its a dell dimension 8400 and i was running it on win xp. Any help that anyone could give me would be greatly appreciated.
