this is a great tool, i will try it at home, i will gonna corrupt my brothers windows xp with lots of games hehehehe.
then try to recover all files that erased on that hdd, and after i will reformat to ubuntu so my brother will force to obey his great Older brother that loves ubuntu Linux.

:P :P :P

If the original drive was formatted FAT or FAT32, then the file names are all kept in the file allocation table at the start of the disk... and if this probable reformat has wiped the file allocation table, then the filenames, the directory structure, all that stuff is gone.

If that is what happened, I don't see any way to get anything better than all the files with random filenames.
