My minifaq:

convention:
/dev/hda1 ==> source
/dev/hdb1 ==> target

- do the usual stuff for the target like fdisk,
mkfs, mkswap, etc.

- mount the target partition example is:
mount /dev/hdb1 /mnt

- Copy source to target except /proc and /home.
create subdir /proc and /home on target.

cp -ax /root /usr /lib /dev .. <etc> .. /mnt
mkdir -p /mnt/proc /mnt/home

- edit the target /mnt/etc/fstab to reflect the
target hdd, ex. /dev/hdb1

- update mbr of the target using lilo or grub
for lilo, you can do:
chroot /mnt
lilo

- test the 2nd HDD if it will boot.

General way to do it. You can script the whole
thing since fdisk, mkswap, mkfs and lilo are
just done once. the recurring part is cp and
editting the fstab. you can use sed to auto edit
fstab.

mind you this also applicable for:

- Cold Standby Mirror. backup your pri. hdd
everyday or every week. really great if you
trashed the pri. disk because of human error,
and not hardware problems. RAID mirror will not
help you with recovery since it's human error
which is involved.

- upgrading the primary HDD to a larger HDD.
