HELP!!! I moved my videos to an external HD and now they are gone.

I moved two movies to an external HD, and archived them. Now all the files are gone, I tried using Disc Doctor but it couldn't find the files. I'm hoping its because the demo version has a size limit of 10GB, and the files were closer to 26GB each.

I am going to be boiled alive if I can't produce these files.

Or, I'm going to get a lot of dirty looks and people will say bad things behind my back, but its still bad.
