This is your problem.  FIPS does something bad that FreeBSD doesn't like.

It's rather bad in that it does not adjust the clustersize when it splits
partitions.  1.2GB disks have something like a 64k clustersize; dropping
it to 700mb may actually need a 32k clustersize, but FIPS doesn't change
it.

You got it.

That is the latest nuance:  the DOS fs lives but the BSD fs dies. 

It used to be the other way around.
