Diskpart: Format FAT32 via Command Line in Windows 10, 8, 7
Here is how to perform Diskpart format FAT32, as well as how to solve “DiskPart format fat32 volume size is too big” problem in Windows PC.
No matter you are using a pendrive, SD card, USB flash drive, SSD or other external hard drives to store your data, you will need to format it to FAT32 in the following situations.
①If you plan to use the disk on PS3, Xbox or some other games consoles that only supports FAT32 file system, then you will need to format the disk to FAT32.
②If you want your device to be compatible with more operating systems, like Mac, Linux and some other older versions of Windows including Windows 98, Windows XP, Windows Server 2003, etc, the FAT32 is the best choice.
③If you need to connect your hard drive to a NAS device, but the NTFS won't allow the NAS device to access the drive, then you need to format or convert NTFS to FAT32.
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 to format disk to FAT32 via Diskpart command line. You will need local administrator access on the computer to follow these steps.
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.
Although DiskPart is a great choice when Windows Disk Management and File Explorer fail to format hard drive to FAT32, it also shares a common limitation with the other two tools: they cannot format a large drive (over 32GB) to FAT32. When you try to perform such formatting task in Diskpart, you will receive an error message saying "The volume size is too big for FAT32"(as shown in the below screenshot).
