"crashing" ?

Ahh poop! (Not my "exact" word.)
# dd status=progress bs=4096 if=/dev/sdb | gzip > DeadStick.FC30.2019-09-06 34489798656 bytes (34 GB, 32 GiB) copied, 404 s, 85.4 MB/s dd: error reading '/dev/sdb': Input/output error 8425692+0 records in 8425692+0 records out 34511634432 bytes (35 GB, 32 GiB) copied, 459.17 s, 75.2 MB/s
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?
