Actually there are lot of software to recover data from ext3 filesystem . Few are like "rlinux" , "Recover4All" and "Easy recovery" . Though they work on Windows they have good chance to recover your data on linux partition . PS : I am not a expert but I use "Easy recovery" that works for my friend . This is really easy to use software .
