Ah - I didn't know it was clever enough to do that, I had assumed that 
if you forced all the drives they'd all be marked up-to-date.

What should I do if I had 3 different event counts (like this case) all 
fairly close to each other (unlike this case) and I really did want to 
force them all, avoiding a resync?
