Are you facing issues with a corrupted USB drive or simply need to clear its data? Formatting your USB drive can effectively restore it to a functional state. Even if it’s not damaged, a quick format is an efficient way to delete unnecessary files, switch file systems for improved compatibility, and enhance performance. This comprehensive guide will walk you through various methods to format a USB drive in Windows.
Step 1: Format Your USB Drive via File Explorer
One of the most straightforward methods to format a USB drive is through Windows’ built-in File Explorer. This user-friendly approach allows you to manage your storage devices easily.
To begin, right-click on the USB drive in a File Explorer window and select Format from the contextual menu.

Next, choose the preferred file system. If NTFS is set as default, consider switching to FAT32 for broader compatibility with different operating systems. However, if you plan to store files larger than 4GB, stick with NTFS.
To help you decide, here’s a quick comparison of the file systems:
File System | Pros | Cons | Best Used For |
---|---|---|---|
FAT32 | * High compatibility with major OS* Uses less memory | * Cannot store files larger than 4GB* Limited partition size (up to 32GB) | * USB drives* Devices needing cross-platform support |
NTFS | * Supports larger partitions* Handles files over 4GB* Offers on-the-fly encryption | * Poor cross-platform support | * Internal hard drives* Windows system drives |
exFAT | * Unlimited file and partition sizes | * May require additional drivers on Linux | * External hard drives* Large file storage on flash drives |
You can also modify the Volume label to personalize your USB drive. Ensure the Quick Format option is checked, and then click Start to begin formatting.

A warning message will appear, stating that formatting will erase all data on the disk. Click OK to continue.

Optional Step: During the process, you may select an Allocation unit size. It’s advisable to keep the default setting of 4096 bytes, which is optimal for most modern USB devices.

Step 2: Format Your USB Drive Using Disk Management (Healthy Partition)
Press Win + X to access the Quick Menu, then select Disk Management. This will display a list of all connected storage devices and their partitions.
Locate the USB drive under the corresponding Disk (Number). Right-click it and choose Format.

A format dialog box will appear, allowing you to customize the Volume label and select the default File system for your USB drive.
Ensure you have checked the Perform a quick format option and keep the Allocation unit size set to Default. Once everything is set, hit OK.

You will receive a confirmation pop-up. Click OK to proceed with the formatting.

Step 3: Format a USB Drive in Disk Management (Unallocated Space)
Sometimes, if your USB drive is not assigned a drive letter or its file system is compromised, it may not appear in File Explorer. In such cases, Disk Management is an invaluable tool for formatting drives that are unrecognizable.
Your USB drive will appear as Unallocated. Right-click the unallocated space and select Create New Simple Volume.

Follow the prompts in the New Simple Volume Wizard to create a partition and format it. Click Next to start the process.

When prompted to Specify Volume Size, keep the default value and hit Next.
Optional: If you plan to create multiple partitions, you may choose a smaller volume size, leaving additional space for future partitions.

Next, assign a drive letter to your new partition and click Next.

You will then choose a File system, specify the Allocation unit size, and input a Volume label. Ensure Perform a quick format is selected, and click Next.

The wizard will provide a summary of your selected options. Click Finish to execute the formatting process.

Step 4: Format Using Command Prompt
If you are comfortable working in Command Prompt, you can format your USB drive directly through it. First, determine the drive letter of your USB from This PC; for instance, we’ll assume it is E:.
Launch Command Prompt as an administrator and input the following command:
format /Drive letter name/: /FS:NTFS /Q

You will see a message prompting you to Insert a new disk for drive letter. Press Enter. The subsequent display will provide details of the file system, volume label, and quick formatting options. Press Enter again to finalize the formatting process.
Step 5: Use the Diskpart Command to Format Your USB Drive
To proceed with formatting through Diskpart, open Command Prompt in administrative mode and type diskpart
.
The Command Prompt will indicate that Diskpart is currently active. Enter list disk to view all connected drives, including your USB drive.
Identify your USB drive’s number and input select disk #
. Once highlighted, type clean disk #
.

Your USB drive will now show as unallocated space. You can return to Disk Management for further steps to assign a drive letter to this section.
Step 6: Format Using PowerShell Commands
Starting with PowerShell, open it in administrator mode.
In PowerShell, type the following command to display the list of storage devices:
Get-Disk

Once you have identified the USB drive—let’s say it’s shown as Number 1—enter the command to clear the disk:
Clear-Disk -Number 1 -RemoveData
When prompted for confirmation, type Y and hit Enter to proceed.
The formatting process will complete in a few moments, after which you can return to Disk Management to create a suitable volume.

Step 7: Formatting USB Drive via Local Group Policy Editor
On occasion, formatting restrictions may stem from accidental policies that prevent formatting or enact write protections. These restrictions may not be addressed by the methods detailed above.
To resolve this, access the Local Group Policy Editor by entering gpedit.msc
in the Run dialog.
Navigate through User Configuration -> Administrative Templates -> System -> Removable Storage Access, and locate Removable Disks: Deny Write Access. Double-click on it to modify its settings.

If the option is set to Enabled, formatting will be blocked. To rectify this, change it to Disabled and click Apply -> OK. With this option disabled, you can now format your USB drive using standard methods.
