I have a 32GB USB Stick which was working fine till I attempted to open a file on it for the first time in a week or so. The files seem to disappear once they have been copied to the USB then it's been removed and recopied.
Although they don't disappear all at once, I could open one folder that originally had files it but would be empty..then do another which would be fine and contain filers. Then repeat these steps but this time all the folders would be empty and files gone!
I've tried formatting the device in quick format and the other longer option as well as checking for errors and bad segments but nothing seems to be wrong and the format completes successfully but then the above reoccurs.
