max(block_id+blocks-1) returned 1142032 so i'm not in luck with that possibility. thanks for your help !
One other less obvious thing that people often overlook - make sure your tablespace is not in a nologging mode. You can't perform blockrecovery (or any other meaningful recovery) on it. While the rman recovery will technically "succeed", a routine dbverify will throw corruption again.
