A step by step description of what I used to move my data from a 45 GB
IDE disk to a larger, new 200 GB disk back in October, can also be found
at the following post:


This may come handy, so feel free to give it a look.  It more or less
includes everything described by Jerry McAllister and shows how the
whole process can be done using the command line tools of FreeBSD.
Some times, sysinstall doesn't work quite right for me; so I prefer
using fdisk/bsdlabel/newfs when I have a choise.
