I've noticed that every time I eject a disc, I see some scratches. I put in the Star Trek Digital Copy disc into my iMac disc drive and when it ejected, I found a lot of scratches on it. My Sims 3 and Spore discs also have similar type of scratches. Is anyone having this problem or am I taking out the disc wrong causing the scratches? This is my first iMac and I'm a bit sad about this as I do not want to lug this computer back to the store to get a replacement... And if I return it, do I have to bring it back to the same store or can I go to one that is closer to me?
