My 16GB was full and is now empty! Please help

My 16GB cruzer was full of documents and working fine on Tuesday. It stayed plug in all night and Wednesday morning when I opened it it was completely empty. No power failure. Nothing done on my part. Is there a way I can rescue data on stick. The light goes on and it pop up on my computer like usual. Thanks

you can try data recovery software You can download the demo version for free.

It happened to before… I just reset the computer and its works…

How does one “reset the computer”?  Reboot I understand.  :stuck_out_tongue:
