I have a small portable USB drive with a 40GB capacity, which is formatted as a FAT32 file system. Viewing it with Windows' disk management utility I see fat32 I want to reformat that drive, so I did what I used to do in such cases:

c:\>format d: /FS:FAT32
The type of the file system is FAT32.
Enter current volume label for drive D: nicbackup

WARNING, ALL DATA ON NON-REMOVABLE DISK
DRIVE D: WILL BE LOST!
Proceed with Format (Y/N)? y
Verifying 38146M
The volume is too big for FAT32.

and was most surprised by the error–message I got after an endless wait informing me that the volume is too big. Considering a FAT32 volume ought to be able to be 8TB in size, my surprise was great. I quickly found fat32format which does what I expect of it very quickly.

c:\>fat32format d:

A simple if time–consuming chkdsk /r d: ensures the volume is ready for use.
