You might find it easier to use  NetBSD install cd or floppies to 
fdisk and partition the new disk with just single new disk as wd0 so 
you don't risk the existing data. You can crash out before actually 
installing or go through install to check you have a working 
destination system. Then fit old disk back as wd0 and new as wd1 and 
newfs then restore to destination partitions on wd1.

If with your -s option you start at offset 63 you need to subtract 63 
from the total sectors or possibly use '$' in place of size in order 
to autosize to end of disk.
