Deleted a movie file, then used testdisk and Data Rescue 2 to recover it. The file was not overwritten at all, and the disk was not written to after the deletion of the file. This is what testdisk recovers: Can't play the movie file, and it has a different md5 hash compared to the file before it was deleted (which is to be expected), but the file size is exactly the same. Data Rescue 2 and Photorec recover the single .mov file, and it will open in Quicktime, but only displays a black screen. In VLC, nothing will come up. Same results on FAT32 and HFS+ devices.
