Way 1. Format the Drive Using Diskpart

Step 2. In the elevated Command Prompt window, type diskpart and hit Enter to access the Diskpart utility.

Step 3. Type the following commands in order and hit Enter after each one to format the drive.

• list volume
• select volume * (* refers to the number of the volume you want to format)
• format fs=fat32 quick or format fs=ntfs quick

Way 2. Format the Drive Using MiniTool Partition Wizard

As mentioned above, the Windows tool has a limitation on formatting a large drive to FAT32. In addition, the formatting process may be stuck on some errors like  “Windows was unable to complete the format”, “The format did not complete successfully”, etc.

MiniTool Partition Wizard breaks through these limitations and can be used to convert NTFS to FAT32 without data loss, convert MBR to GPT, change cluster size, and so on.
