Recovering Data from Overwritten Ext2 Partition

[dodle]

I am trying to recover some files from a hard drive that was primarily an Ext2 partition (there was a small ntfs partition at the beginning). The current filesystem is fat32 but formatting did not finish so it is unreadable at the moment. I am currently running photorec on it but it hasn't found anything yet. Does anyone have any suggestions on how I might be able to recover the files. Should I reformat it back to Ext2 before trying to recover? This is the first time I have attempted file recovery on a filesystem type other than ntfs and fat.

----- Edit -----

Okay, photorec just started recovering files. I was able to do it without reformatting the drive. Hopefully it doesn't just search for files based on extension.
