Guys, thanks in advance. I just bought a Sandisk Ultra USB 256GB and I want to copy my documents from C:/Mydocuments to the USB (F:). It won't copy. It says there's an error. I attached screen shots to help explain this.
An unexpected error is keeping you from copying the folder. Error 0x800701B1 - a device which does not exist was specified.
