Moved files

I recently lost a lot of important files cuting and pasting them on a flash drive that stoped to work while the files were moving to it.

The main files I want to recover where entirely moved from my hard drive. So I tried to use Recuva but the result wasn't so good, looks like it recovered files that were previously deleted there and not all the files that where moved and lost now.

I made a few tests with Recuva in another hd, moving files and trying to recover them. Recuva didn't found any, even with deep scan.

Is that anything different when files are moved, they are not considered deleted? Or maybe I'm doing something wrong?
