when I inseret my usb in my pc an error message pops up so I attempted to do windows error checking for my USB but it got frozen so I restarted my pc and when I do it again it comes up with a message "This disk contains file system errors that windows cannot fix" when I click on the drive everything is gone but I can see how much space I have used and how much I have left, so is the a chance I can recover it back.
