I've seen this question posted many times; but always in reference to discs. I'm try to "burn" an image to a USB stick and I'm getting "Disk not Empty". I'm using a SanDisk Gator 8GB. There is something on there called U3 which I cannot remove. I've tried using DISKPART to clean the USB stick and recreate a fresh partition and then format it. U3 is still there. Is there a workaround? A way to get ImgBurn to proceed without the disk being empty?
