Thank you for your answer. Over the weekend I have attempted recovering all photos - even those marked as irrecoverable and it turned out most actually could be recovered without issues, hooray! Pictures that were supposedly replaced by others that should have been present at the same time were fine (while files supposedly overwriting them were indeed lost due to video as reported). Some of listed conflicts were by older images, eg 9955 from few months ago supposedly overwrote recent 9457 (as filenames wrapped around). On the other hand, some of pictures marked by green weren't recovered immediately - actually all pictures after the first overwrite by a video file seemed lost. But fortunately those later pictures were found during deep scan and still got recovered. Seems as if the file system of the card was confused what is present where.

I have recently deleted photos from an SD card during upload to computer, which died during making backup of said photos (yes, lesson learned - always make another backup before deleting from SD card, even if time difference is 15 minutes). From SD card I managed to recover most photos, but there is weirdness with others: some photos taken in January were claimed to be overwritten by some later photos and videos. However, those photos were present on the SD card at the same time and got deleted together - the only possible way of overwrite I can imagine is if camera shuffled data during its delete process. Is it possible to "force" Recuva to grab data that is on the supposed image spot, even if it is (partly) corrupt, or is that data surely lost and really got overwritten and destroyed? Deep scan returns the same files as fast one, so I fear those photos are indeed lost. I recovered files using the free version of Recuva, though I am willing to buy the paid one should it enable these extra thingies and help me save the remaining files.
