You need the device NOT to be mounted when you do the cp. This may mean
you have to turn off your auto-mounter, or (better still) just log out of
your Desktop Environment entirely, and log in as root on a text console
for this operation.
If the device is mounted, that will interfere with the raw byte writing
you're doing. The results are unpredictable.
