    It looks like the iMac's Hard Drive is going to die.

    Save the data, as soon as you are able to start the computer.

     

    Perform Apple Hardware Test

     

    But if my guess is right I don't think there is much to do other than change the hard disk.

    It may be worth trying a Safe Boot - http://support.apple.com/kb/ht1455 - this sometimes works when other methods fail.

     

    Use Firewire to backup by manually copying files to another disk.

    Your hard drive is about to fail.  If you can get the system to boot make a backup using SuperDuper or Carbon Copy Cloner.

     

    Unfortunately you have learned the hard way.  Drives do fail.  As soon as you unpack your new iMac you should make a backup and then keep a regime of backups.  I do this weekly.

    How can i backup in target mode?

     

    http://support.apple.com/kb/ht1661

     

    The above page says once you have started up in Target Disk Mode you can copy files to or from the target computer. The target disk behaves like any other external disk.

     

    You could simply copy your Users folder as it normally contains most data - it is best to do this first as it will be quick.

     

    I prefer to use Carbon Copy Cloner to clone the whole of my old disk into a disk image on my new computer so that I can reinstall my old OS and all files later.

    You could try Carbon Copy Cloner as I described earlier - old versions are still free but I think the latest version in Demo mode will do all you want.

     

    After you have cloned the old Mac to an image on the new one you could try reformatting your old Mac - this will destroy all data on it.

     

    If this works either reinstall from DVD or from disk image via Carbon Copy Cloner.

     

    Install AppleJack for future use - it sometimes works when other methods fail - I have never known it do any harm.

    I had similar disk issue with lion, and I did not have to replace the imac or internal disk, but did reformat the iMac internal disk as you did. Did you ever get your computer back up? Just curious.
