"Auto Power Saving" and "Auto Power Off"

There were also a few people that suggested this was user error and he was not pressing the right section before searching for his files.

It's very easy to think you are copying files on the keyboard then find that apparently only the folders are copied and the files are missing. Firstly the keyboard has to be in Style mode for copying style files, then in Voice mode for voices  etc. etc. If you don't remember to do that first the files really won't be there. And if you want to view them to check,  you have to be in the appropriate modes again or they won't apparently be there even though they could be. There are plenty of opportunities for misunderstanding in normal use, without the need to invoke corruption or auto power off issues.
