Sure, but that's still just copying part of a file - it's not doing
anything special. 'cat /dev/hda > /dev/hdb' is probably just as good.

So long as your new disc isn't smaller than the old one, it works. If
it's bigger, you have to repartition to get the extra space back. You
end up with the same partitioning scheme and filesystems. 'dd' is a
pretty poor Ghost.

Cheers,

Alex.
