geez. Definite security issue there, definitely can't let us find out
what disk you are trying to newfs (incorrectly). And yes, what you are
hiding IS your problem.
Like Otto said, "man newfs"
Hint: the opposite of "block" is "raw".
Double hint: as Otto indicated and I hinted at, what you were doing
before was wrong. They don't let you do that anymore.
