Would you > mind taking a look at that now too :-) Hmmm. The last bit is less than ideal. If all drives are faulty, but runnable in the array with at least one drive of redundancy, the best way to put good drives in service is one-by-one mdadm --replace. That lets the redundancy fix any errors, and doesn't load down the problem drive any more than ddrescue would. And it has the benefit of increasing reliability as you go. If you don't have any redundancy left, then ddrescue of all readable drives is reasonable.
