Had some success finding files using Disk Drill, but wife vetoed purchasing the Pro version (which would actually allow me to recover them). Looking at the previews, the files do seem to be there, but with some corruption. I’d guess that maybe a quarter of the pictures had some level of corruption on them.
Now trying again with photorec, since I’m being told to try one of the free options. Already seeing several thousand files and I’m just a few minutes in. Looks like it’ll take around 15 hours to image the whole drive though.
