I was using my five day old MacBook Pro until, out of nowhere, it started freezing and slowing down. Eventually, it froze completely to the point where I can barely use it for the next three minutes, so I had to force shut it down by long-pressing the power button. I turned it back on, only to find a progress bar below the spinning gear, but after they both disappear, the Mac shuts down. Two more attempts yielded exactly the same result as the first attempt. I ended up having to erase the drive (since it was locked) and reinstall Mountain Lion from the recovery partition, until it told me (three hours later) that the hard disk was damaged and the only thing I can do was restart and try again. At the second attempt, I tried repairing the disk, only to find that it can't be repaired and that I had to erase it (again). I erased it and went for a second attempt at reinstalling OS X, with the same outcome as the first attempt. A third attempt, same thing. The irony of the situation is that S.M.A.R.T. reports that the hard disk is verified, so I have my doubts that the hard disk itself is damaged. Any ideas as to what is causing this bizarre series of events?
