You can probably use /stand/sysinstall to slice and partition 
the new disk.  It might be easier.   I have never done a second disk 
that way.  I always just use fdisk/disklabel/newfs 
But, I do the initial installs with the sysinstall on the boot CD
and that's the same thing.   You just have to select the right drive
and follow through.   Make sure you mark the new FreeBSD slice
as bootable in that screen (after you create the slice, put the
highlight on that line and select 's').
