Actually, vfs_bio, not msdosfs, in pre-2.2 versions of FreeBSD can
destroy all partitions on all disks, not just msdosfs partitions, if a
single msdosfs partition with a cluster size of > 16K is mounted, even if
it is mounted read-only.  msdsofs partitions larger than 1GB have a block
size of > 16K, so they have the problem.  Smaller partitions may also
have the problem, e.g., ones that were shrunk from larger than 1GB to
smaller than 1GB using a shrinker that doesn't change the block size.
