Oh, wait, for 4 devices there are 24 permutations - and you need to do it 4
times, substituting 'missing' for each device - so 96 trials.
4320 trials for a 6 device array.
Hmm. I've got a 7 device raid 6 - I think I'll go an make a note of how it's put
together... <grin>
Have a look at this section and the linked script.
I can't test it until later
