Is this really necessary, I tested a 7.3 install and each drive worked on 
it's own easily when I tried to simulate a drive failure.  With 8.0 it 
doesn't look like it will do that for some reason, I can still mount the 
second HD but cannot boot off of it.  

Can anyone on the list that was a software RAID 1 scheme similar to mine
( /dev/md0 = / ) confirm that their system will boot off either drive?

thanks..
