Clarification please.

Did you mean 'umount' rather than 'mount?
I would have used umount /dev/sdc1
I don't understand what exactly is done by piping mount (or umount) into 
grep sdc.
I would have used dd rather than cp- I was under the impression that cp 
only copies files, not 'bare metal' data.

Any comments appreciated.
