So my MacBook Pro was thought to be perfect but the DVD drive is acting up. At first I noticed it when I tried to reinstall Leopard when it first arrived, it wouldn't read the Leopard DVD but it would read the Applications DVD. I called up Applecare and they sent me a new Leopard DVD. When that arrived I tried it and it did not work. This got me to thinking so I hooked up an external DVD drive and viola, the original Leopard install DVD read perfectly. I have since burned several DVDs(SL and DL) and CDs and they have been fine. But just today the drive failed twice in a row when trying to burn a DL DVD. I will attempt a third but I don't think it will end up well. Combine that with the not reading part and I think I may have to send this in to Applecare eventually. My question is twofold. I purchased this off ebay brand new in the box 8 days ago. Can I go to an Apple store and exchange it? If so can I keep my original HD? If I have to send it in to Apple care how many people here have done that and had scratches on their machines when they are returned? I've sent my 06 BlackBook in several times and the last time had it mauled. Thanks in advance.
