Hello, I have an Aopen DUW 1608/12x DVD/RW drive. It has always been slow to start, which seems like a motherboard problem because my CD drive is the same but was ok in another computer. But now, sometimes, the drive doesn't find the disk. It asks for the disk to be inserted. When I click on the DVD/RW drive symbol in My Computer and click on explore, for example, the symbol now says the drive is a CD Drive and explore shows that the DVD is empty. If I restart the computer it may correct the problem or if I put another DVD or CD in the drive and open it and then replace the DVD that didn't work it may now work. Is this part of a motherboard problem. I don't what technical info is relevant but the system has an AMD XP Athlon 2800+ with 512 RAM an Abit NF7S2 Motherboard. Windows XP SP2.Thanks for your help.
