    1. Plug in your USB Flash Drive
    2. Open a command prompt as administrator.
    3. Find the drive number of your USB Drive by typing the following into the Command Prompt window:
      Type diskpart
      Type list disk
      The number of your USB should be in the list. You’ll need this for the next step. we'll assume that the USB flash drive is disk 1.
    4. Format the drive by typing the next instructions into the same window. Replace the number “1” with the number of your disk below.
      select disk 1
      clean
      create partition primary
      select partition 1
      active
      format fs=NTFS or format fs=FAT32
      assign
      exit

    Hope this helps, The Dev.

    The clean command works great (clean all wipes all data), just remember to ABSOLUTELY make sure you select the correct disk when doing this!

    For USB sticks, you should never use NTFS on it, preferably you use Fat32 with 32K allocation size. It's just what they're designed for. Running NTFS on the flash drive will diminish performance, as will running an allocation size smaller than 32k (such as 4K). You can also format to exFAT, but not all OS support that.

    I highly recommend using the SD Card Organisation's SD Card Formatter for USB sticks (yes it does support USB sticks) as well as for SD cards etc.

    If you don't format using the above principles, you will most likely get lower drive performance.
