Best way or the quickest?
I do it the wrong way and the quickest way possible:
cat /dev/hda > /dev/hdc
cat /dev/hdb > /dev/hdd
That would make an identical copy of your two drives on the primary
channel onto the secondary channel. It will work regardless of hard drive
sizes only if the new drives are larger. No need to format, repartition,
or any of that. The new drives will appear to be the same size as the
older ones in every respect.
Other members of the list will tell you how evil that is, but I say hard
drives are cheap these days.
