I tried It but never got "Main boot region needs to be updated. Yes/No?" and this was the result:

sudo fsck_exfat -d disk2s1

I tried the instructions in section 7.4 and copied the backup to the main; still no luck--same as above.
I tried to search and write a partition; maybe I'm not doing it right, but no luck.
I tried chkdsk on Windows, but the filesystem in RAW.
I haven't reformatted it, but I have used EaseUS to recover much, if not all, of the data, but it didn't keep my folder structure and I'm sure not everything is there/uncorrupted.
Any ideas? Thanks in advance. I tried to do my own research before asking, but now I'm stumped.
