--- Comment #4 from Kirk McKusick <mckusick at FreeBSD.org> ---
The first few sectors on the partition (8K for UFS1, 64K or 256K for UFS2) are
reserved for disk labels and boot code. The newfs utility does not manipulate
(and in some cases is prevented from manipulating) this area. The gpart(8) (or
disklabel(8)) utility is used to update this area. If it is desired to zero
this area, one of these utilities shold be used to do that.
