"crashing" ?

Ahh poop! (Not my "exact" word.)

That was on my USB 3.1 port.
Not sure this is a problem. How big is /dev/sdb? What do you expect dd
to do when it hits the end of the drive?
Hmm. You have two "32GiB ...copied" lines up there. From the same run?
Ah, no, that is your "status=progress" getting cut in half by the dd
error and the in/out report. So that's ok.
So, what's bad about the above?
