You mean ddrescue is reporting bad areas as good? If this is the case it 
is a serious bug.

I guess the algorithm has become complicated enough that some 
verification means are needed. I am working on a "test mode" where the 
map of good/bad areas can be specified and the resulting logfile can be 
compared with the map to verify that ddrescue is copying the data properly.
