Hi.

To me it sounds like a dying hard drive

See this recent thread which has discussed the problem.

The hard drive is fine the dfrag software has somehow unmounted and damaged the disc DO NOT USE DRIVE GENIUS.

Now I am gonna have to do a full restore thankgod I have my time machine back up.

It is quite a know fact to not use Drive Genius, as it does more harm than it does good, except when needed.

Mac OS X does not fragmentize like Windows does, so you're better off without such tools, unless you need to repair and recover data.
