If you're getting errors when trying to format your USB flash drive in Windows File Explorer (such as "Windows was unable to complete the format"), you can still format the drive using the Command Prompt. This How.com.vn article will teach you how to erase and reformat your flash drive using the DiskPart tool in CMD using your Windows computer or laptop.
Things You Should Know
- Plug the USB into your computer, then run CMD as Administrator.
- After using the commands "diskpart", "list disk", and "select disk", type "clean" and press "Enter".
- Use the command "create partition primary" to further format your USB drive.
Steps
- Plug your USB drive into your computer. Plug it into one of the various USB ports on your computer to continue.
- Normally, you'd format a USB drive by right-clicking it and selecting Format from the menu. You'll only use Command Prompt if that other method does not work.
- You can also use this method if you can't see the USB drive in File Explorer.
- Open Command Prompt as an administrator. To do this, press the Win key on your keyboard and type "cmd" to search for the program.[1]
- Click Run as Administrator from the results list that appears.
