Hi Matt,
The ext4 don't have data checksum, but have metadata checksum, which would
probably be corrupted as well, as I reinstalled my Linux over the same
partition the FreeBSD was using, and by
now I have a lot more files on it than I had on FreeBSD.
If you look at the forum post I created, you'll see that I ran the command
smartctl as well, and it shows that there's no problem with the SSD, it's a
new SDD, some months of use.
I ran the command inside FreeBSD:
