I think there is another good software which i found in my case to do formatted hard recovery. One can easily recover Mac files or Windows files with this software which supports both Windows and Mac OS so just visit the given URL's for more information:
I suggest you to search “data recovery tool” on google. Actually, there are plenty of recovery tools you can choose from.
But, if have no idea, I think you can try a free formatted drive recovery tool: http://www.formatrecovery.blogspot.com/2013/02/recover-...
It helped a lot as the flash drive of my girl friend was mistakenly formatted. It is really worth a shot.
I hope this information helps you.
