On Windows 10, the ability to format a USB flash drive can come in handy in a number of scenarios. For example, you might want to reformat a new or used removable storage device to make sure it doesn't contain any malicious code. Or if a thumb drive is inaccessible because of data corruption. Maybe you received a flash drive using a file system that isn't compatible with your system configuration. Or you're planning to give the drive away and want to make sure personal information doesn't go along with it.
Hi, If your USB flash drive has data on it or maybe an earlier version of the Windows 10 installation media for example. Do you have to format the USB flash drive manually in windows (right click and format) before using the Windows Media Creation.
Whatever the reason, Windows 10 ships with several tools to format virtually any kind of storage, including USB flash drives, using File Explorer, Disk Management, Command Prompt, and PowerShell.
In this Windows 10 guide, we walk you through the different ways you can format a USB flash drive to quickly erase its contents or fix problems when the device isn't recognized.
Warning: Using any of the instructions outlined below will erase the contents on the drive you select. If you have any important files, you should back them up before proceeding.
How to format a USB flash drive using File Explorer
To format a USB flash drive using File Explorer, use these steps:
- Open File Explorer.
- Click on This PC from the left pane.
- Under the 'Devices and drivers' section, right-click the flash drive and select the Format option.
- Use the 'File system' drop-down menu and select the NTFS option.Quick tip: If you're planning to use the removable drive on Windows 10 as well as on macOS systems, you may want to select the exFAT option for compatibility. However, if you're also thinking about using the device on a Linux machine, FAT32 is the best option, even though you'll be limited to 4GB file sizes.
- In the 'Allocation unit size' drop-down menu use the default selection.
- In the 'Volume label' field, type a label to quickly identify the flash drive in File Explorer. For example, workFlash.
- Under the 'Format options' section, select the Quick format option.Note: The 'Quick format' option only deletes the file system table and the root folder, but the data may still be recoverable on the drive. If you don't check the option, a full format will take place, and it'll perform a scan for bad sectors and writes zeros in all sectors to delete the data. As a result, the process can take a long time depending on the size of the storage.
- Click the Start button.
- Click the Yes button.
Once you complete these steps, you can start storing documents, pictures, videos, and other files on the removable drive.
How to format a USB flash drive using Disk Management
Using Disk Management, there are at least two ways to format a removable drive. You can format the drive to rebuild the file system table and erase its content. Or you can delete the partition containing the file system and data, which can come in handy to fix problems with storage.

Formatting is the term used in Windows operating system to erase all content in the drive and make it to initial state. You can format both internal and external drives in Windows 10. USB devices are prone to damage and file corruptions due to usage on multiple computers. So, there are many situations you would like to erase all the content on your USB and format it like a new one. Windows supports file systems like NTFS and FAT for formatting drives.
Unfortunately you can’t use the Windows formatted USBs on your Mac for saving content. Though you can mount the drive to view and copy the content, you can’t write on the drive. In order to write on the USB drive on Mac, you need to format the device into Apple supported file systems like APFS or Mac OS Extended. Similar to Windows 10, you can format USB drives on Mac using Disk Utility app.
1. Formatting USB in Windows 10
First off, ensure your flash drive is already plugged in to your PC. To verify that your system recognizes your flash drive, press “Windows + E” shortcut keys and open “File Explorer”. On the left pane, click on “This PC”. You will see a screen like the one shown below. Under “Devices and drives”, locate your Flash drive.
Check USB Drive in Windows
As you can see above the Flash drive is labeled H in our case. It already has some content occupying the space. Before proceeding with formatting, ensure to copy the content from the drive. Otherwise you will loose all the stored content on the USB drive.
Right click on the flash drive and select “Format” option as shown below.
Format Option
On the window that appears, you’ll get the details of the Flash drive such as capacity, file system and allocation unit size. Check the “Quick Format” option and click on “Start” to begin the formatting process.
