That normally includes MSDOS filesystems that are 512MB or greater. When you use FIPS to shrink an MSDOS FS from, say 1GB, to say, 400MB, the cluster size does not decrease, and there is still a problem. Note that you are still in danger EVEN if you mount the MSDOS FS read-only. The problem appears to be fixed in the 2.2 series of code. John dyson@freebsd.org
