Thanks, but I just copied some 30GB between the FreeBSD and Windows
10 computer and didn't see a single error message.

I tried r330300, but the behavior didn't change.  Maybe I should go even
further back in time.

One possibilty is the new BIOS I installed on my Ryzen (FreeBSD) box.
I checked that the settings are all optimized, but who knows what Asus
changed?
