I suggest removing the drive from the device manager, and rebooting, letting the system reinstall the drive, and then trying it again. Ive never had any luck with those cd cleaners or whatever that you can buy. but if you want to, try that. You could reformat your computer with a boot floppy disk, but then your pretty much banking on it being a software problem and not a hardware one.
EDIT: Cool, Im a donor now. Score
