|Third party tools can format partitions to FAT32.|
Below is a chart showing cluster sizes.
for FAT32 are as follows:
512MB to 8,191MB = 4KB
8,192MB to 16,383MB = 8KB
16,384MB to 32,767MB = 16KB
Larger than 32,768MB = 32KB
NTFS - All partitions on a PC = 4KB default
FAT32 can waste lots of space due to the large cluster size.
