I posted a similar question on another thread but I think it might be more appropriate to this one. My Macbook Pro 13' with Lion all of a sudden cannot access my hard drive. When I start it, it goes straight to Utility OS. When I ask it to show all available hard drives it only shows "Recovery HD". Now onto my questions: 1. Could a possible overheating problem have caused a physical damage to the hard drive? I've heard about Mac and overheating problems before. 2. When I try to Reinstall The System through Utility it says "This Disc Is Protected" and I cannot go further. What does that mean anyway? I went to a random Mac repair store here in London and they charged me 220£ to recover my hard drive, which I thought was pretty insane. I'm not sure what to do at this point. I'm even considering erasing the hard drive and reinstalling the system from scratch but, if the problem is with the hardware, I'm not sure this will fix anything. I'm really really disappointed with Apple...how can a major problem like that happen on such a new product? I haven't dropped it on the floor or anything like that.
