No, so far nothing seems to make a difference, and I cannot even get much
information from it. When I ran ddrescue, everything hummed along smoothly,
no bad sectors, right up until 99.9% complete (literally!), then there were 2
errors, 3072 B (total, I believe), and these bits could not be read even when
I let it run for 500+ passes.
Running testdisk now, on both iso and img files -- different copies of the
same source. I am getting a message now, the run is about half-finished:
check_FAT: Unusual number of reserved sectors 4 (FAT), should be 1.
check_FAT: Unusual media descriptor (0xf8!=0xf0)
Warning: number of heads/cylinder mismatches 64 (FAT) != 255 (HD)
Warning: number of sectors per track mismatches 32 (FAT) != 63 (HD)
FAT12 54360 71 48 54361 11 50 12288 [Firmware]
The message is the same on both. However, it ought to be ext3, not
fat-anything; unless these sectors are in reserved system space or something,
this seems to be wrong.
I don't even use this drive in connection with any fat filesystem; only my
flash drive (the one I mentioned, which also failed) uses fat-32. I have one
ntfs drive; the rest are all either ext4 or ext3.

Recovered
images (img and iso) are saved, and taking up space, but I
cannot determine if there is any useful content in what was recovered.
Can you not just mount the ISO?* Then you'd be able to see what was able
to be saved with standard tools. Or even get jiggy and open up a hex
editor is you're so inclined...
Best,
