Scenario: FAT32 option not available


I want to format my SD card with Disk Management, but it seems that the ‘format option’ has no ‘FAT32’. The file system only shows me “NTFS”. How can I format it to FAT32? What should I do? Is there any solution?”


Why FAT32 option not available?

Sometimes you may need to format drive to FAT32. For example, many devices only recognize FAT32 and do not recognize exFAT/NTFS (such as PS5, PS4, XBOX360, some TVs, and some XP machines without exFAT patch). Thus, many users would like to format the drive to FAT32. Generally speaking, you can format it to FAT32 file system easily and successfully in Disk Management.

Can't format to FAT32

However, sometimes you might find FAT32 option not available in Disk Management. Why this problem appeared? It is usually due to that your partition is larger than 32GB. Because the default Windows format option only allows the FAT32 partition on drives that are 32GB or less. In other words, Windows built-in formatting tools like Disk Management, File Explorer or DiskPart won’t allow you to format 64GB SD card to FAT32. And this is why the FAT32 format option not available in Windows 10 or the other versions.
