The rm will fail because gzip removes the original file when it's
finished compressing. However, the other suggestion to pipe straight
through gzip (or other compression program) is better anyway.
I noticed that. I had tested it on a small png file first and
it did not remove it. I bet I just did not refresh my file
manager soon enough.
I am going to test the straight pipe today on my USB3 ports
and see if the overhead slows down the dd enough to stop
crashing dd.
Also going to test another Samsung USB flash drive on
USB3 and see if dd crashes. Maybe it is my ports and
not the drive. Will find out.
Thank you for the tips!
Ahh poop! (Not my "exact" word.)
