  "18.3 Adding Disks" in FreeBSD handbook:
  http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/disks-adding.html

>Description:
  A sample commands to create a new partition (newfs -d0 /dev/da1e) cause
error in at least 6.2R-p8 system.  The command apppers in 18.3.2.2.

>How-To-Repeat:
  Run newfs with -d0 option.  It cause a error.
  In my case:

# newfs -d0 /dev/da0a
newfs: 0: bad extent block size
#

>Fix:

  The next example in the handbook says use "newfs /dev/da1e", so i think
remove -d0 option from the handbook is enough.
