That simply runs ddrescue on the good parts of the disk first
(therefore you get the maximum amount of readable data copied over in
the shortest time span) before trying to read the bad parts multiple
times.

But nothing will change the physical fact that data which is unreadable
(true unreadable, not intermittent) is just that, unreadable, and no
amount of attempting to read it over and over will magically make it
readable.
