I get:
richard@debian-jan13:~$ stat / | fgrep Device
Device: 80eh/2062d	Inode: 2           Links: 22
richard@debian-jan13:~$ stat /media | fgrep Device
Device: 80eh/2062d	Inode: 131073      Links: 5
richard@debian-jan13:~$

I gather that "cp" is then an inappropriate tool.

"tar" is inappropriate for my preferences - I was attempting to use "cp" 
as there would be multiple files &/or directories as input *and* output.

I suspect long term I want "rsync" [ *MUCH* reading to do! ]

Although I wish to avoid "tar", I did get inspiration for a brute force 
method - I'll try it first before commenting.
