I had a portable drive that I had put some video movies I had made and had put all my pictures I had in my computer onto this drive. Everything disappeared (for no apparent reason, not sure why) and I have a recovery program. I ran the program, but in the deleted files it say they are empty and when I recovered the video files, they will not open. Is it common for picture files not able to be recovered? Or would you even now why they all disappeared to begin with? I hadn't even been in the drive, but everything disappeared.
