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.

How can i backup in target mode?
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.

the imac eventually appeared on the desktop of macbookpro and i was able to backup the files i needed.
i also went to utilities[imac] and tried to verify..
Verifying volume “Macintosh HD”
The disk “Macintosh HD” could not be unmounted
which is different to the response via the macbookpro utilities yesterday.
Verifying volume “Macintosh HD”
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid record count
Volume check failed.
Error: Filesystem verify or repair failed.
its looking bleak i know for the Imac HD as i am 200km from AASP and would have to ship it.
still at least i got the 2013 files today as i had 2012 already backed up.
if u have any other advice i would be grateful and ty again for your help

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 have been offline for a while and have just managed to erase the Imac and after verify it says hd ok.
I was unable to install mac osx as the superdrive just spits its out again, however i have installed mac osx disc 1 via my MBPRO with the Imac in target mode.
I was very happy to see the installer appear BUT it does not show show a destination and i have waited for a least 30 mins as per other articles.
I wonder if you have any soultions to help me now as its so frustratiing to get this far and be stuck again.
Many thanks in advance

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.
