To quote:
The maximum possible number of clusters on a volume using the FAT32 file
system is 268,435,445. With a maximum of 32 KB per cluster with space
for the file allocation table (FAT), this equates to a maximum disk size
of approximately 8 terabytes (TB).

For whatever reason, Windows XP and Windows 2000 can't format a FAT32
partition that is bigger than 32 GB (problem with their format program).

Also, there is a 4 GB file size limit.

All from the same article that took 30 seconds to find.
