External hard drive issues!

Ok sooooo. I'm stupid. Why I'm saying that is one, I knoe or at least thing I know how this all started. I plugged my hard drive (had everything major in it like EVERYTHING) into my Xbox 360, went to add it to a memory unit and clicked yes by accident after reading it would format my drive... Yea I'm smart... Than being a total idot I pulled it out.. ._. Yea laugh all you want... And than went to my PC (Windows 7) and it said it was a un readable expansion drive. I than later went back to my Xbox to find ish formating it (._.) And went back to my computer with little hope and already the knowledge that it would have a -9999999999999999999999% chance of showing my files.... And I was right... This is probably a no but could I restore my files any way? Like a recovery wizard or something idk I told you I'm an idiot. I had backups of computers on there. RPG maker, game times, run time packs, games, steam files, important docs, like my life was just formated here.... I need some help T_T
