I have a DVD-ROM/CD-RW combo and a CD-ROM both going into the secondary IDE port on my motherboard, and both drives give me trouble. The DVD sometimes scratches my disks or doesn't recognise them and I have to eject and reinsert them. And the CD-ROM keeps spinning down after about 3 seconds. I've tried unplugging one and it makes no difference. Also I had this trouble before and got a replacment for the DVD but it started doing the same thing. Anyway anyone got any ideas what it might be, I was thinking maybe it had some relation to the motherboard.
