USB flash memory storage device (USB flash drive) is lightweight, exquisite, easy to use, easy to carry, and other advantages.

partition parameter occupies 16 bytes. A simple division can be seen: A hard disk can be divided into up to four logical disks (independent from each other ). We can see that there may be many hard disk partitions. Why? This is the reason for introducing Extended partitions.
