But to utilize storage space, Microsoft manually limits the max FAT32 size to 32 GB. Therefore, the real size limit of FAT32 should be 2TB or 16TB. Nowadays, most hard drives are 512-byte sector or 4 KB sector drives. On a hard drive with 4 KB sectors and 64 KB clusters, the real size limit is 16 TB. On a hard drive with 2 KB sectors and 32 KB clusters, the real size limit is 8 TB.

On a hard drive with 512-byte sectors, the real size limit of FAT32 is 2TB. Actually, the reason why you can't format to FAT32 is that the FAT32 file system has size limit (32 GB), which is set by Microsoft manually. If they format the drive in Windows, the system will not display the FAT32 option.

Nowadays, they want to extend the storage but they find that the system can't format the drive to FAT32. Some people may have old devices (such as PSP, XBOX360, some TVs and some XP machines without exFAT patch) that only support FAT32 file system.
