I noticed there hasn't been any mention of attempting to recover your deleted files from your local disk. If you haven't tried it yet it is worth a shot. There are a few software solutions out there that will scan your disk for files that have been deleted. On Windows I have used Piriform's Recuva[1] and on OS X I have used PhotoRec[2], both have worked rather well. It is worth noting that the longer you wait to try the more likely the sectors are to be overwritten with new data. (And you should back up any files currently on the disk). I know it is a long shot at this point but some chance is better than none. Good luck.
