Full guide: Diskpart format to FAT32 in Windows 11/10/8/7

Usually, you can format a disk to FAT32 in File Explorer and Disk Management. However, if you fail to format hard drive to FAT32 successfully via these two built-in tools and receive formatting errors like "Windows was unable to complete the format" or "The format did not complete successfully", you can turn to DiskPart.exe tool. Below are steps about how to format USB to FAT32 with Command Prompt. You will need local administrator access on the computer to follow these steps.

Warning: The formatting process means data loss, so back up everything important before proceeding. You can back up to cloud or local drive.

Step 1. On your keyboard, press the "Windows + R" at the same time to open "Run" Window, then type "Diskpart" and click "OK" (click Yes if prompted by the User Access Control).

Step 2. DISKPART will open in a command prompt window. And type the following commands in sequence:

• list disk: see all disks connected to your computer, and you need to identify which drive needs to be formatted by size.

• select disk 1: select the disk which contains the target drive.

• list partition: list all partitions on the disk.

• select partition X: X refers the partition number that you need to format.

• format fs=fat32 or format fs=fat32 quick

If the disk is set to be write-protected, you need to run extra different commands to format it to FAT32 via DiskPart.

"list disk >select disk 1 >attributes disk clear readonly >clean >create partition primary >format fs=fat32"

Then you can format write-protected disk using DiskPart with a success.
