I've been reading other posts on other Vista forums and have found out that other ppl are having the same issue or similar. Some are like my situation or the drive is listed in device manager but with an error next to it so they are unable to use the CD/DVD ROM drives. Obviously there is a problem with Vista taking ppl's drives off of there pc's. PPl have told me to remove the drive from the mother board and reinstall it and see if it fixes the problem, well thats all fine and dandy but should'nt be having to do that just to use our drives and Vista at the same time.
