Yes, that seems to be the best bet so far. When you have
the result files, check them with an image viewer. Also
keep in mind that magicrescue _can_ (and will) recover
files that have been deleted intendedly, so prepare for
duplicate files. (The script I wrote would deal with
those special cases, too.)

No, that is fully correct. This setting will create a FAT-32
filesystem, which "Windows" can typically use (with the specific
limitations of FAT and "Windows", of course). "ExFAT" is a
proprietary extension of FAT aimed primarily at SSDs, USB
sticks, and memory cards.

You can forget about the NTFS part. :-)
