I was working on a project yesterday morning. I finished saved my work to my thumb drive. shut down my laptop. I left my thumb drive in the usb port. I came back to work some more opened Excell went to open the file but could not find the removable disk f that is where it was earler. So I pulled it out and put it back in a message pops up USB Device Not Reconized. So I put it in my wifes lap top and get the same message. Can someone please help or have I lost all files on this removable storage.
