Photo Recovery

http://www.cgsecurity.org/wiki/PhotoRec

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted.

Restoration is a freeware program by Brian Kato that restores deleted files no longer in the Recycle Bin. The good news is that it works not only on Windows 9x versions, but also on Windows NT, 2000, and XP — even in NTFS! It fits neatly on a floppy, since it is only 406 KB in size (and the Windows 2000/XP version is less than half that size), but you can also run it from your hard drive. I recommend you be prepared to use either option.
