I've been using the compaq multibay and dvd/cd-rw drive, but It's giving some problems. When I insert a CD, often I hear the dingdong sound and the drive disappears, then about 30 seconds later, it comes back and goes over and over again. I have to disconnect it, and try again. Sometimes this solves the problem. A while later, it occurs again, with the CD already in. It'll just suddenly disconnect then come back again, but at least it does come back, sometimes its impossible to get to work. The fan in it keeps coming on and going off while it is trying to start working when a CD is put in, and the D drive disappears from My Computer. When I eject the CD, the D Drive comes back.
