I bought this MacBook on eBay a week or so ago, it's showing as ~8 weeks old right now and it was new in box with all the wrappings when I first bought it. I haven't used the SuperDrive at all until today when I installed Microsoft Office and the Garage Band sound pack. I'm positive I didn't cause this damage; one because I have taken care of this MacBook like it was my baby, and two because I don't see how this would have been possible by me. The picture is kinda hard to see, sorry it was difficult to try and get a good steady shot of it. I'm clueless as of what to do about this, any ideas?
