Okay: rsync or union.
I had browsed the manpage for rsync and found it roughly as lucid and
straightforward as the manpage for tar. ;-)
But I'll have another look and check union, too.

Gets complicated , don't it? In my case, either directory tree could
have changed but HD1 is canonical so:
Any new files on HD2 (that don't exist on HD1) can stay, but
Any files on HD2 with same path/name as on HD1 must be same as
on HD1, and
Any files on HD1 that are absent from HD2 must be copied over.
So I have some more reading to do.
