Unreal. At just two years old, my favorite piece of equipment has failed. I'm lucky I backed up the 12,000+ images I have, but if they can't recover them, I may have lost a few recent ones along with recent documents. I'm also really glad I bought the Apple Care protection plan - I'd hate to try to fix this myself.
Lesson of the decade: back up your files, no matter how good or new your computer is! You can bet I plan to enhance my backup routine, that's for sure.
