4. Look under the Devices and drives section to find your connected USB.

   

5. Right-click on your USB drive icon and select Format… from the context menu. A small configuration window will pop up.

   

6. Configuration formatting options:
   • File System: Open the drop-down menu and select your preferred format (exFAT, NTFS, or FAT32).
   • Allocation Unit Size: Leave this setting at its default.
   • Volume Label: Type a new name for your USB drive if you want to rename it.

     

7. Ensure the Quick Format checkbox is ticked. This skips scanning the drive for bad sectors to save time. Click Start.

   

8. A warning pop-up will appear stating that formatting will erase all data. Click OK to confirm. Once a final pop-up says “Format Complete,” click OK and close the tool.

   

Method 2: Using Disk Management

Windows Disk Management is a powerful built-in system tool designed for advanced configurations, so it can be used to format your USB flash drive even if it is not shown or recognized by File Explorer. It bypasses these graphical issues to successfully access and format the drive.

Steps to format USB using Disk Management:

1. Connect your USB drive to the PC.

   

2. Right-click on the Start button (Windows logo) on your taskbar and select Disk Management from the Power User menu, or press Windows Key + X and select it.

10. Click the Format button.

    

11. Wait a few seconds for the progress bar to finish. The status will update to “Healthy,” confirming your drive has been successfully reset.

Method 4: Using Command Prompt/Diskpart

The DiskPart tool inside Command Prompt is a powerful text-based command-line method that can be used if your drive is severely corrupted, write-protected, or showing errors in File Manager. It ignores all the glitches and forcefully attempts to read, write, or format the drive.

Here are the steps to format USB drive using DiskPart:

1. Connect the external USB flash drive to your PC.

   

2. Click the Windows Search bar, type cmd, and click Run as administrator next to Command Prompt.

   

3. Type diskpart and press Enter to launch it. The command line prompt will change to DISKPART>.

   

4. Type list disk and press Enter. A table showing all storage drives on your computer will appear.

   

5. Look closely at the sizes listed. Identify your USB drive by its storage capacity so you do not accidentally format the main Windows hard drive.

   

6. Type select disk X (replace X with the actual number assigned to your USB drive, such as select disk 2) and press Enter. You will see a message saying “Disk X is now the selected disk.”

   

7. Type clean and press Enter. This completely clears the drive’s existing layout and removes all partitions.

   

8. Type create partition primary and press Enter to make the drive usable again.

   

9. Enter format fs=exfat quick and press Enter.

   

Tip: You can replace exfat with ntfs or fat32 depending on the file system you need.

10. Type assign and press Enter to give your formatted USB drive a letter so Windows can detect it in File Explorer.

    

11. Type exit and press Enter to close DiskPart, then close the Command Prompt window. Your USB drive is now ready.

    

Method 5: Using Windows PowerShell

Windows PowerShell is a modern command-line shell and scripting language designed for advanced automation. Using PowerShell commands, you can format USB drive much faster than clicking through visual interfaces. It is highly effective to secure large-capacity USB flash drive formats.

Here’s how to format a USB drive using PowerShell commands:

1. Connect the USB flash drive to your PC.

   

2. Right-click on the Start button (Windows logo) on your taskbar and select Terminal (Admin) or Windows PowerShell (Admin) from the menu.

   

3. Type Get-Volume and press Enter.

   

4. Find your USB drive in the list and note its assigned Drive Letter (example, E, F, or G).

   

Warning: Windows PowerShell may or may not give a warning to confirm the format.

5. Type the following command and press Enter (make sure to replace X with your actual USB drive letter):

   Format-Volume -DriveLetter X -FileSystem exFAT -NewFileSystemLabel “MyUSB” -Full:$false

   

Tip: You can change exFAT to NTFS or FAT32 based on your preference, and change “MyUSB” to whatever name you want to give your drive.

6. PowerShell will display a small progress bar. Once finished, a status summary showing your drive letter, file system type, and healthy status will appear on your screen.

   

How to Format a USB Drive on Mac?

Formatting a USB drive on a Mac gives you a clean USB with fewer software glitches and file architecture. Apple provides two built-in methods to safely wipe and configure external storage. Remember to back up all your data before formatting the USB drive.

You can choose between a visual menu or a text-based terminal shortcut to format a USB drive. But before that, here is a breakdown of the available USB file system formats on Mac.

macOS USB File Systems

File System	Maximum File Size	OS Compatibility
APFS	2^63 – 1 bytes	macOS 10.13 and newer only (incompatible with Windows)
exFAT	2^64 – 1 bytes	Windows, Mac, Linux
Mac OS Extended (HFS+)	2^63 – 1 bytes	Legacy Mac-only (Read-only on Windows)
FAT32	4 GB	Virtually all older and modern devices

Method 1: Using Mac Disk Utility

Apple’s Disk Utility is the system’s core storage manager. It handles everything from partition layouts to drive health monitoring. When you format a USB drive here, the tool erases the partition and creates a clean partition map as per Apple’s optimization protocols. It is the safest choice for standard storage.

Steps to format USB using Disk Utility on a Mac:

1. Plug your flash drive into an open port on your Mac.

   

2. Go to Applications > Utilities and double-click Disk Utility.

   

3. Click the View icon in the top-left corner and select Show All Devices.

   

4. Click the top-level hardware name of your USB drive in the left sidebar.

   

5. Click the Erase button located in the top toolbar menu.

   

6. Configure the format:
   • Name: Type a new name for your flash drive.
   • Format: Select your preferred system (APFS or exFAT) from the dropdown menu.
   • Scheme (Optional): Choose GUID Partition Map.

     

7. Click the Erase button in the pop-up configuration window.

   

8. Wait for the progress bar to finish, then click Done.

   

Method 2: Using Terminal

Using the macOS Terminal gives you low-level access to Darwin, the core Unix operating system underlying macOS. One advantage of using this Terminal command to format USB flash drive on a Mac is that the previous method can hang if the USB drive has corrupted blocks or an unusable file structure, but using this diskutil command in Terminal will forcefully format the USB.

How to format a USB drive on Mac using Terminal?

1. Plug your USB flash drive into your Mac computer.

   

2. Navigate to Applications> Utilities and double-click the Terminal app.

   

3. Type diskutil list and press Enter to display all connected drives.

   

4. Look at the storage capacity sizes to find your USB drive letter layout. Note its identifier node located in the right column (example, disk2 or disk3).

   

5. Type the following command and press Return. (Make sure to replace diskX with your USB identifier)

   diskutil ereaseDisk exFAT MyUSB GPT diskX

   

Tip: You can replace exFAT with APFS if you want a Mac-exclusive file structure and rename MyUSB to any label you prefer.

6. Wait a few moments until the command line shows Finished erase on diskX.

What to Do If Your USB Won’t Format?

Solution 1. If the drive shows “Write-Protected” or error messages: Use text-based commands in Command Prompt (DiskPart) or Mac Terminal

Solution 2. If the drive is not recognized or shows “Unallocated Space”: Use the Disk Management method to format the USB drive

Solution 3. If the Format wizard freezes: Use Windows PowerShell to run the direct script to format.
