Solution 2. Format USB Drives (Larger Than 32GB) to FAT32 Using PowerShell

One of the most common file formats for removable storage devices like USB drives is FAT32. However, Windows 10 does not have a built-in way to format USB drives to FAT32. This can be a problem if you need to use FAT32 for compatibility reasons.

Fortunately, there is a way to let you know how to format USB to FAT32 using PowerShell. 

Step 1. To do this, open PowerShell as an administrator.

Open the start menu and search PowerShell on the search bar. Right-click it and select "Run as administrator."

Step 2. Run the following command: Format- /FS:FAT32 + drive letter

e.g. format /FS:FAT32 D:

Be sure to replace D: with the actual drive letter of your USB drive. Once the command has been executed, your USB drive will be formatted to FAT32.

Solution 3. Remove Read-only Using Diskpart

If your USB drive shows read-only, you can turn to diskpart to remove write protection. Then try to format the device again.

To clear the read-only attributes of a USB drive using Diskpart, follow these steps: 

1. Open the Command Prompt as an administrator. 

2. Type in "diskpart" and press Enter. 

3. Type in "list disk" and press Enter. This will list all of the disks connected to the computer. 

4. Type in "select disk 1" and press Enter. Replace "1" with the number of the USB drive you want to modify. 

5. Type in "attributes disk clear readonly" and press Enter. This will clear the attributes and make the drive writable again. 

6. Type in "exit" and press Enter to exit Diskpart. Your USB drive should now be writable again. If you continue to experience issues, you may need to format the drive or try a different USB port on your computer.
