The clues missing from that instruction is that you should locate the 
_path_ (not only the name) for the _disk_ (not partitions on it).

Yes, I agree lsblk is a good tool here: It a) shows topology by default 
which may intuitively help distinguish a USB stick often with a single 
partition from an internal harddrive with several partitions that would 
be devastating to accidentally overwrite, and b) lists explicitly which 
are disks and which are partitions.

(I only discovered that tool recently)

Thanks, Paul!
