I've got a late 2007 iMac.  I downloaded Mountain lion and the installer began, but then abrubtly quit with the message "Installation Failed".  It mentioned there was a disk failure and that I should run the disk utility.  I ran verify disk and it failed, so I then ran Repair disk and it also failed with the following error message:

 

Incorrect number of file hard links

Bad hard link creation date

(It should be 3273005659 instead of 3314922810)

Hard link record has data extents (id = 33147751)

Error: Disk Utility can't repair this disk...disk, and restore your backed-up files

 

Now any time I reboot the installers appears like it is going to start, but immediately pops up the message "There was a problem installing Mac OS X.  Try reinstalling."   Its an endless cycle.

 

Any ideas on how to fix this?  If it is going to require reformatting the drive, is there any way to copy all my existing files off onto an external hard drive?

 

Any help would be much appreciated!!
