Well, that's what I exectly started to test. As I told earlyer,
when plugging in a new disk it did duplicate the existing disk
onto the new one right away. The above mentioned test was if both
copies are independant usable as first drive for recovery.

I won't start the final test, the one where I put both disks
together again, to see how it recovers teh inconsistent system,
until next week, since I need the machine to woork the next 3 days.

That's why I used stripeing on my game machine :)
