unable to format 64GB SD card to FAT32

Usually, the most common issue is that your SD card is too large in volume that exceeds the FAT32 file system format limit (32GB) on Windows.

Like the USB drive, SD cards with 32GB or lower storage are set to FAT32 by default. While exFAT is set as the default file system for larger SD cards with 64GB or 128GB. As some special devices only support the FAT32 file system, like the 3Ds SD card, it requires users to format the SD card to FAT32, no matter how large it is. 

Due to the limitation of FAT32, the Windows system doesn't support creating a FAT32 partition on a more than 32GB disk partition. As a result, you cannot directly format a 64GB memory card nor USB flash drive to FAT32. So what will you do when you must format a 64GB SD card to FAT32?

Fortunately, besides the Windows built-in utility, you still have a chance to fix 'can't format your 64GB SD card or format USB flash drive to FAT32' issue. A third-party & powerful FAT32 format tool can help resolve this issue effectively.
