Perhaps, a free hard disk recovery tool is what you are looking for: http://not-formatted.blogspot.com/2013/02/recover-data-...
Do you save some new files on the same drive?
The new saved files will rewrite your original data and erase it forever. So, you should stop using it right now.
In the future, you are also supposed to copy all your important data at least on two separate drives in case of similar problems.
