Because? Remember that the flavour of FAT in use is defined *entirely* by the number of clusters on the volume...

According to the sources for the FAT filesystem driver (which you can get from <http://opensource.apple.com>), you can look at f_fssubtype in the statfs structure, which you can retrieve using statfs() or similar. See man 2 statfs. This isn't exactly a Cocoa question, BTW... you should probably have asked on darwin-dev or one of the other lists.
