Windows "Format" command in Explorer cannot delete partitions. Therefore you can use the command DISKPART from the command line to remove the partitions of the USB stick and format it.
You will lose all data on your USB drive if you make a mistake. We are not responsible for any data loss.
We recommend that you only connect one USB stick at the time of formatting and deleting partitions. This way, you won't format the wrong USB drive by mistake.
