    Well, which is it - what you say in the title, or what you say in the body of your post ? ?
  2. Does it say "the usb disk is not formatted, do you want to format it now?" or with error code "cannot be initialized" or so?

    Possible reason can be usb corruption, file system error etc, see this article fix usb not formatted error for the step by step fixes.
