If you can't find the files by removing this drive and running RECUVA on another PC with this drive as a slave or in some USB case you call up DRIVESAVERS to see how much and if there is a chance at recovery.

I can't imagine folk today not knowing about backups. It's a common discussion and with cloud storage like Onedrive, Dropbox and others, why isn't what you can't lose on a memory stick, cloud or other disk?
