I have been using my 16 GB SanDisk USB regularly for the past year. Today when I plugged it into my computer a screen popped up that says, "The file or directory is corrupted and unreadable." Then another screen pops up that tells me I need to format my USB. Is there a way I can format the USB without losing all of my files currently on it? Thanks.
