I do NOT want to send my hard drive out if I do not have to. Any ideas???

I quick formatted my drive and then installed Windows XP. I then realized afterwords there was some files on the drive that I forgot to backup. Is there any good recovery software programs recover data after a quick format and then installed Windows. I did try use one program but no luck (Active File Recovery by LSoft Technologies) the same company that make Killdisk. PLEASE HELP! I NEED THIS DATA!
