Many of them, yes. Some is still guesswork. And of course you can only do this if your computer/phone/tablet can read exFAT in the first place. So if you want a solution that works, say, on the current Jolla phone as a self-contained "reformat this card" script, you cant read and use those parameters.

But it's what I did, of course: I installed exFAT support on a desktop PC and tried to read whatever was visible about the layout of the file system.
