I have a dell dimension w/ windows 7 the original dvdrw drive(E) stopped working repaced with a liteOn ihas524 both optical drives were IDE the E device is SATA . Computer didnt recognize the E drive at first. changed settings to RAID on Drive was then visible and will play but wont burn.
You shouldn't be using raid for the optical drive, try setting the bios to PATA/IDE compatability.
