I just bought a 2010 15" macbook pro off ebay, its in great shape, 45 cycles on the battery, works well but when i put my windows install disc it was making a scraping noise. The noise got worse (far worse) when i moved the laptop to the point where i could hear the drive slow and it ejected the disc. I have applecare until December 22 2013 is this an issue they would replace the superdrive for? Never had an issue with this disc in the past and I have used it to install windows 7 a few times on differant machines
