    First of all, thank you very much for clicking on this thread, i am desperate at this point and would do anything to restore my hard-drive (if possible).

    This is my problem at the moment:
    (I'll add as much detail as possible for you to assess my situation)

    I have a Macbook pro 13" with a Windows partition.
    I was running my Windows 7 on Bootcamp when my Macdrive8 program alerted me of the unmountable mac disk.
    I immediately restarted my computer and tried to boot from the MacOS but the computer got stuck on the loading screen.
    After waiting for 15 min (with no avail) I restarted the system and booted from my Windows.

    After googling for solutions, it seemed like my harddrive became corrputed and i tried these methods:

    Solution 1: used my MacOSX installation DVD to repair my Mac
    Result 1: In the repair option, the installation CD would not recognize the Mac Drive and would only show the bootcamp partition. The Mac drive would not even show up.

    Solution 2: used the "/sbin/fsck -fy" command
    Result 2: Did not work, and told me that it could not repair the disk

    Solution 3: Booted from Windows and used the Macdrive8's built in Disk repair feature (
    Result 3:fml, it could not repair the disk

    By now, I'm exhausted and frustrated, and i hope someone in this forum could help me repair my Harddrive and save my files. A total wipe-out&reformat would be the last option for me as i want to same some sentimental files on the corrupted drive.

    Sorry for the long read. Any help would be very much appreciated. :(

    You could try connecting your computer to another Mac. Although it won't boot it might still be mountable by another computer using target disk mode and a firewire cable.

    It is installed on the same HD. I will try the methods on the link, thank you.

    None of the methods on the site seem to work. I also ran disk utility from the install disk and clicked repair. this is what it showed me:

    keys out of order
    rebuilding catalog B-tree

    Error: File system verify or repair failed

    sigh* is there any other method that i can try?

    by the way, would turning on and off the computer using the hold power button method damage the computer? i think i did this about 30 time today and am getting worried

    Can you revive any of the files to an external HD? Is it accessible from the Windows partition? Did you reinstall OS X as I said in my post above?

    Mac Hardrive corrupted, Windows Partition Working

    Hi Blacms, though I sympathise with you, it is comforting to know I am not the only one with this problem. I have a 27" iMac and bootcamped it with Windows 7 on the other partition. Occasionally, mine is doing exactly what yours is. The Repair Utility on the startup disk will not fix the Catalog B error and the only way to fix it (that I have found) is to restore the Mac partition from my TimeMachine Backup. Not sure about your case but I have just checked booting it up with Windows 7 and found I can access the user files that have been added today so these can be retrieved before I restore the backup (from 2 days ago). Sorry the news is not much better. I don't know what it is about Windows 7 that is corrupting the Mac partition????? not sure.. I thought I could have my cake and eat it too.. !! Hmm not quite. Does anybody out there have any pointers as to what we could fix to stop this from happening? Has it got something to do with the way Windows 7 exits maybe? Hope someone can shed some light on this..
