On am on my 2nd super drive on my 2.16 C2D Macbook pro. This one has trouble reading some disks occasionally. I bought a dvd cleaner with some tiny brushes on it that has helped it a lot, however it is not perfect. I want to sell my MBP on Ebay. I was wondering how should I explain or should I tell what is wrong with it. It does work but not perfect. I guess I will take a beating on the price because this makes the machine not 100% What would say in the listing?
