I have the previous model Macbook pro that i recently had wiped and updated to 10.6.8. I recently noticed there was a small dent underneath the disk drive. It was small and I thought i didn't have to worry, but when I tried to put in a Nirvana cd, it would make noises for a few seconds (like normal) but then just eject the disk. It's a brand new disk with no scratches and I tried blowing into the disk drive, but to no avail. I need to use this disk drive I have to mix a Nirvana cover album and I can't play the drum parts if I have nothing to listen to! Please reply quickly...
