The only way that I know of for recovering info from a formatted disc(partition) is through third party recovery programs that does it through DOS.
The program is installed on a bootable disc and it is ran after booting to the disc. A different drive should be used to write the recovered data to...Data files are fairly easy to recover....while photoes and video files are much more difficult and some may never be recovered at all.....that is by using the programs that are available to the public.
