Why we need to partition USB drive ?

USB hard drive or memory card, as the removable storage, is the most ordinary device in people’s daily life. They are widely used for storing important data and files, system backup images, for example. One of the most important advantages of them, when put into use is their portability. People can transfer data and files between computer and different removable storage devices conveniently and smoothly.

Sometimes, you do need to multi-partition a Kingston or SanDisk USB drive, such as creating different partitions to store different data or creating partitions on an unallocated USB. Therefore, the question of how to partition USB drive will come into your sight. Actually, you can perform this task using both Diskpart and free partition manager. Connect USB drive to your PC first and make sure it is detected by Windows.

The following are the detailed steps of using diskpart to partition a completely blank USB drive.
