Why do 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, etc. With USB drive, people can transfer data and files between computers 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 bootable USB. Therefore, the question of how to partition USB drive will come into your sight.

Can you partition a USB drive?

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

Firstly, open Diskpart by pressing Windows key and R key (same time), type in “diskpart” in the pop-up window, and then hit Enter. For Windows 7 and XP, click on Windows icon, select “Command Prompt” & click “Run as Administrator”. For Windows 8, press Windows key and X key (same time), click “Command Prompt (Admin)”.

Note: To execute a command line, please press Enter key after each move.

Secondly, enter “list disk”. Then you will see all your disks (it is important you know which disk is the USB key).

Thirdly, enter “select disk X” (X stands for the USB key). Enter “create partition primary”-> “list part”, and then enter “select part 1”-> “active”-> enter “format fs=ntfs label=’Tabernus’ (the label is optional).
