    AI: Has this USB stick ever worked properly before, or has it always shown as "no media" since you got it?
    It worked but I know it was a fake. Yesterday I inserted it, but it appears as a USB drive, and when I click it it says "Insert a disk into the drive".
    AI: When you plug the USB stick into your computer, does it show up in Windows Disk Management, and if so, what does it display (e.g., unallocated space, no media, errors)?
    In Disk Management it appears "No Media" and don't possible format
