    +1 Same problem after about 5 minutes of install on my '11 MBP 13" and then you start hearing the hard drive and then the installer complains there is a problem.  No hard drive problems experienced prior to ML install.  Should have waitied but was real excited.  Now I have to wait and figure out how to fix this problem.  Only if the new iMac was out, I could just buy that, restore from time machine, and be good to go while figuring out the MBP issue later.

    Saying "it cant be your hard drive because it has had no problems before" is like saying, "My car engine cant have a problem because it was working before I went on this cross country road trip".

    No luck on the PRAM reset for anyone but JerikoFox?  That's too bad.  Sorry guys.  Thought I had found the solution.

  • DilJaey Level 1 Level 1

    Tried PRAM, no luck.  Went through verify and repair in Lion disk utility and everything verified and green.

  • ss1776 Level 1 Level 1

    Same issue.


    I couldn't get back to Lion. Had a spare hard drive and used that to restore my backup, then restored the time capsule backup on to my Macbook Pro. Now I'm back on track but don't have Mountain Lion yet.




    I'm going to give the PRAM reset a shot maybe this weekend. I spent enough time trying to get my Macbook to boot again after Mountain Lion installation messed it all up.

    Similar Issue.

    I have MBP Oct 2011.

    I do not have any back up disc or drive available.

    It says that "Error in installation due to MaC HD is damaged and can not be repaired".

    I can not go back to oSX Lion also.


    Please help!!

    Same exact issue - with respect all these hard drives can't be going bad simultaneously

  • DrFreeman2 Level 1 Level 1

    I have got the same issue as well. I have posted a screenshot of it here. I tried making an image of the hard drive using disk utility but it says that the size is too large. It seems that there is a problem with ML installation files!


    Anyone has a solution please?





  • jbwhitehurst Level 1 Level 1

    Still no luck for me. Resetting PRAM didn't seem to do anything. I called and talked with Apple.  They said an engineer was looking into the problem and they would call back within 24-48 hours. Hopefully, they can provide a solution.  Too big of a coincidence that all these hard drives would fail at one time.

  • ss1776 Level 1 Level 1

    So you're saying all of our hard drives have gone sour simultaneously?


    Well, in my case, I had the same error as the screenshot DrFreeman2 posted. I have since reformatted the Mac OS partition on my hard drive and then restored from time machine.


    And then I re-ran disk utilities. Everything was fine. I fixed some permissions that were broken, but the disk itself was all green. No issues found.


    So this has to be a ML specific bug. I hope Apple is working on this.

  • DrFreeman2 Level 1 Level 1

    My computer does not allow me to reformat the drive. Apple Genius is not really helpful either as they are booked in London (UK) until 31st of July!


    I am trying the instructions here to create a separate ML installation drive and see whether I can install it that way!


  • mirq Level 1 Level 1

    having same issue. disk repair says to format and reinstall. i can get into ML but once I start loading apps, especially iCloud apps like mail, calendar, contacts, it just freezes. in activity monitor there are tasks that run with high memory usage, like over a gig of memory being used. brings the whole machine to a standstill. have to restart the machine every time it slows down so i can back up my files to an external.

  • DrFreeman2 Level 1 Level 1

    After so many restarts into ML and Lion recovery files, it eventually allowed me to erase the drive!


    I am now reinstalling Lion. Followed by the upgrade to ML!

  • ArtyYeo Level 1 Level 1

    I had the same HDD error installing Mt. Lion onto a late 2009 Mac Mini.

    Went on to Disk Util and did a Verify and the HDD came out fine.

    Re-installed Mt. Lion and it hit the same issue.


    Took out my old Snow Leopard Disk and rebooted it from CD (thank God for CDROM !!!) and ran Disk Util from this old OS and did a Verify. This time it found lots of errors and suggested Repair option.


    Repair failed as well.


    I'm doing an Erase and re-install. This is getting to be quite a painful installation.


    Strange that the newer Disk Verify cannot pick up any errors. Why?

  • Gordon B. Isnor Level 1 Level 1

    I had the same problem. Attempted to install ML numerous times, and every time it failed, telling me that my hard drive was damaged. Each time, I was able to somehow eventually get back to Lion. When I run Disk Ulitity from Lion, I receive no error messages. Apple Support told me to take the computer to a service centre and get the hard drive replaced. Given that I have witnessed no problems until now with the hard drive, and that Lion reports no errors, I'm skeptical that there is a hard drive problem.
