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?

It is 64 GB.

Ah, badness then as you say.

Had you tried ddrescue, a dd-like command with an ability to step past bad areas and proceed with the rest?

Cheers,

Trying it right now.  Had to drop the if= and of=.

Thank you for all the help!
