Came back from holiday to find my 18month old work iMac wont boot up.


Opened Disc Utility in safe mode and says "Can't be repaired" and i can't get into the hdd

Works network won't accept Time Machine so I never got round to getting an external drive and setting it up. (Yeah - I know)


As a last resort, got a 2tb drive and am trying to create a new disc image. Been "reading whole disc" for 3 hours, not even a quarter of the way through. 


REALLY not wanting to have to reinstall adobe again and get all by browsers back to how I like them.

IT seemed to suspect a software update issue - one of their macbooks failed exactly the same way last week. But can't find any chatter about it.


Any ideas?

iMac, OS X Mountain Lion (10.8.2)

    Some posters here have had better luck with Disk Warrior for stubborn disk repairs. I haven't used it but in your situation I would most certainly give it a shot because if you can't fix it you will need a new hard drive.

    Did you try running DU from Startup by pressing "c" before you hit the power button? I can't tell by your post if you had tried this.

    pressing "c" before you hit the power button?


    The C key will do nothing unless you have bootable media inserted:





    For the best experience with startup keys, press the keys immediately after the startup tone plays.


    If not using bootable media, for Lion or ML, boot holding Command + R or Command+Option+R.



    For the OP:


    I agree with RRFS - give Disk Warrior a try.

    When i switched on, the progress bar takes an age to get to 99% then the machine powers off.


    By using cmd-r I was able to get to "osx utilities" which gave me 4 choices


    1. reinstall from time machine - didn't set it up
    2. Reinstall OSX - don't want to wipe the machine so haven't done this yet
    3. Get help online - using macbook so don't need to
    4. Disk Utility - that gave the above jpg


    Burning a 'New Image' DMG of the disk onto an external drive and will see if that helps.
    (tried making an uncompressed one, but it failed overnight, so going for the DMG)
