How To Format USB Drive from Command Line

Formatting a USB Drive can be pretty straightforward. You plug in the USB drive and find it Windows File Explorer, and right-click > Format. While do this via GUI is simple and easy, if you want to repeat this for several USBs or automate this action, you probably want to do that via the command line to run as a batch script.

Today we will go over how to format USB drive via the command line.

Type “DISKPART” and Hit Enter, from the diskpart prompt, type “list disk” and hit enter. This should give you something look like below.
