as long as the original data is not overwritten, the data can be recovered.
here's a free partition recovery software that i used when i messed my partition up.
good luck.
so did you manage to recover your data?would like to know if you are successful.according to me the first step should be to make a sector to sector copy of the hard disk to another disk.then you have an identical spare and can try different tools on one without worrying about loss of data.
