I installed Mountain Lion two days ago with no problems except that my 2011 13" MacBook Pro was a bit slower. Yesterday night there was a little shock on the keyboard at which point the system froze. A forced restart was initiated. The system became stuck on the Apple logo screen with the progress indicator animating. I reset the NVRAM. Safe mode was causing system to freeze as well. I repaired the disk permissions and did not see any problems except an issue with java. Today I reinstalled Moutain Lion and the issues still persist:

  • It takes a lot of time to boot
  • Logging into the desktop is really slow
  • Launching Finder freezes the system, or Finder crashes outright
  • The menu bar with the clock Apple and etc disappears
  • Spotlight indexing is endless

I physically opened the laptop today (believing I had nothing to lose), removed the RAM and reinstalled it with no resolution to my issues. I would like to like to know if the Toshiba 500 Gigabyte hard drive is damaged and whether or not I need to replace it. I also have important files that I want to save but the laptop is too slow which prevents me from doing so.

What steps have you taken so far in trying to determine the physical health of your internal hard drive? Also you indicate a "shock". How was this "shock" incurred? –  Mort Nov 8 '12 at 19:53

Do you have Applecare available for this particular MacBook Pro? If so I would recommend taking it to your local Genius Bar and see what they recommend. If you do not have Applecare there are other options available (i.e. manually removal of the drive for further diagnostics). –  Mort Nov 9 '12 at 16:03
    
Backup your most important files first. Then try to take the hdd out and copy it somewhere entirely. Your hdd is probably toast, it's only a matter of time before it won't start at all. Upgrade to an ssd, no moving parts. –  unmircea Dec 7 '13 at 0:59
