How to Format USB Drive or Pen Drive in Windows 11, 10, 8 or 7?

Pendrives or USB thumb drives are very popular in our life due to their portability and tiny size. It is beneficial to create a bootable USB flash drive and even a Windows To Go drive for faster Windows installation. If you purchased a new pen drive without formatting, to use it, you have to format it. Without formatting, you can’t copy any files/folders in your Pendrive. Disk formatting is a built-in feature of every operating system. You may use Windows 11/ 10/ 8/ 7. You can manage the disk in every operating system regardless of the OS version. The operating system can recognize only the formatted disk structure. So, if you have purchased a new Pendrive without formatting or creating a new partition, you need to perform the formatting action to use it normally.

One can perform the pen drive or USB drive formatting using the following methods:-

  1. File Explorer
  2. Disk Management Tool
  3. Command Prompt
  4. Windows PowerShell
  5. USB Disk Storage Format Tool

Note: If your Pen Drive or USB flash drive is write-protected or read-only, you will not be able to format it using these methods. First, you need to remove write-protection or read-only, then you can proceed with further steps.

How to Format a Pen Drive or USB Drive using Windows PowerShell?

Windows PowerShell is an advanced command-line tool. One can also format a Pen Drive or USB Thumb Drive using it. Perform the following recommended steps to format a disk:-

Step 1. Open the PowerShell with administrative privilege.

Step 2. In the elevated Windows PowerShell, type the following and hit Enter from the keyboard:-


The above command will show the disk information. Please note down the number associated with your USB flash drive. For example, number 1 is my USB flash drive.

Step 3. Now, type the following line and press Enter from the keyboard:-

Clear-Disk -Number # -RemoveData

Note: In the above command line, replace the Hash (#) with the number associated with the USB drive that you noted down in step 2. For instance, my USB drive is on number 1, and my command will be the following:-

Clear-Disk -Number 1 -RemoveData

When prompted, type A and again press Enter from the keyboard.

Once you complete the above command, the USB drive will be formatted, and also drive letter will be removed. That means data is erased from USB Drive or Pen Drive and will not be visible in File Explorer.

Step 4. To make it visible in File Explorer, you need to create a partition and assign a Drive Letter. Issue the following command now:-

New-Partition -DiskNumber # -UseMaximumSize -IsActive -DriveLetter NewDriveLetter

Note: In the above command, replace Hash (#) with the number associated with the USB drive you noted earlier and NewDriveLetter with a new drive letter for the USB drive. Ensure that the drive letter is not in use by any other partition on your PC.

For my case, the command will be following:-

New-Partition -DiskNumber 1 -UseMaximumSize -IsActive -DriveLetter D

Once you execute the above command, the partition is created and a drive letter is assigned to your USB drive.

A dialog box will open to format your USB drive. Click on the “Format disk” button.

Once the formatting is completed, it will become visible in File Explorer and will become usable. You can put data on your USB flash drive.

If you are not being prompted to format the disk, you can issue the following command on PowerShell to format it:-

Format-Volume -DriveLetter NewDriveLetter -FileSystem NewFileSystem -NewFileSystemLabel VolumeLabel

Note: Replace NewDriveLetter with the drive letter which you earlier assigned. Change NewFileSystem with the file system format (NTFS, exFAT, or FAT32) you want to format the USB drive. Finally, replace VolumeLabel with the new volume label (name of the USB drive will be visible on File Explorer) for the USB drive.

For instance, we have used the following command:-

Format-Volume -DriveLetter D -FileSystem NTFS -NewFileSystemLabel gearupwindows
