Insert Disk
Boot in single user mode 
(in lilo 'linux single' will probably do it. YMMV)
Partition the new drive
Format the new partition(s) (mkfs.<filesystem type>)
Mount the new partition on /mnt
copy data: cp -aR /var/spool/ /mnt
umount /mnt (optional)
umount /var/spool (also optional)
mount /dev/hdb1 /var/spool
init 3 #or whatever runlevel you normally use

You might want to use LVM. You can still access the original 
/var/spool by mounting it somewhere else (e.g. /mnt)
