Ok, noted thanks Ronni. The OS X is on the MBP drive on board, not on the 
external. Yes, good idea your test below, I might try the test first on a new 
drive to prove the test. Then reformat the drive again and do a CCC of the 
whole (MBP+External drive), then I have my additional backup already sorted on 
top of my TM backup.

Regards

Pete.
