USB drive is a popular portable storage device that helps you to save valuable files. But it needs formatting from time to time for various purposes including freeing up disk space, deleting all data on the drive, removing write-protection from the USB, etc.
Most users would perform the formatting task in a traditional way: right-click on the drive in the File Explorer and select the “Format” option. Quite easy and effective! However, sometimes the formatting process gets stuck in the middle and throws weird error messages like “Windows was unable to complete the format”. In this situation, you can try formatting the USB drive in Command Prompt.
Command Prompt (also called CMD) is a command-line interface in Windows. It can execute every entered valid command. To format pen drive using Command Prompt, do as below:
Step 1. Connect the USB drive to your Windows 7 computer and make sure it is recognized successfully.
Step 2. Search for “cmd” in the “start” menu, right-click on Command Prompt and select “Run as Administrator.”
Step 3. In the Command Prompt window, type the “diskpart” command and press “Enter” to run the Diskpart tool, and execute the following commands in order: to format USB drive.
•list disk: list all the disks in your system.
•select disk #: replace # with your USB drive disk number. Ensure you select the correct disk number.
•clean: delete all partitions on the USB drive
•create partition primary
•format fs=ntfs quick: format your USB drive to NTFS. Also, you can replace “ntfs” with “fat32” or “exfat” to format it to FAT32 or exFAT.
The steps of how to format USB using CMD Windows 7 can be applied to format corrupted or damaged hard drives. But if you need to format a write-protected USB, you have to add the command “attributes disk clear readonly” between “select disk” and “clean” commands in order to first remove the read-only property.
Command Prompt is a great choice when you cannot format a USB drive in File Explorer, but there will be times when it fails. For example, when you try to format a large hard drive, which is over 32GB in size, the formatting process won’t continue, and the error message “The volume is too big for FAT32” will pop out. Besides, without a clean graphical user interface, there is always a risk that you type a wrong disk number and lose important data.
