USB files disappeared, please help?

Seems to me you didn't "safely remove hardware." Have you tried searching in your PC. Try recent documents in your start menu or any temp files on your pc.

When you remove your usb drive you have to click on the icon on the bottom right corner and "safely remove hardware" and wait for it to prompt that is is now safe.

98% of the time you can just remove a drive and no harm will be done but I guess your one of the unlucky ones.

For some drives there is an option in your device manager to optimize the preformance and not have to do this.

Sometimes the USB receptacle on the computer (or drive itself) collects tiny particles which blocks the connection between the two devices...I would blow canned air into both connections and then try again. A restart of your computer might do the trick as well. If you did NOT format the drive then it should work just fine.

I had this problem not too long ago.. my usb drive had died. Try using it on another pc. If you are able to access the drive, don't worry the files are still there, you just need to use some kind of recovery software to view them.. you can go to http://www.usb-data-recovery.com/ and download a free version just to see if that helps.

sounds like a driver issue . does the usb have disk, if so your disk driver is corrupt reinstall it then will find disk
