dd would be one way. Use fdisk or sysinstall to create a disk label on the
new disk with the partitions sized and named as you want. Then run:
dd if=/dev/ad0s1a of=/dev/ad1s1a bs=64k
...for each partition (except swap), where you would use the appropriate
device names-- if is the source, of points to where you are writing to. It's
best to do this in a shell after booting off a FreeBSD CD, so that the on-disk
filesystems are not actively mounted when you copy them.
The FAQ has a more complete discussion and alternatives like using dump and
restore, I believe.
