Hey there, Amanuel0.
As long as you don't write anything else on your drive, you may still have a change to recover your data. Take a look at this article: http://pcsupport.about.com/od/filerecovery/tp/free-file-recovery-programs.htm, it has a lot of options, so hopefully at least one of them works for you.
Good luck!
