I tried to do some more revival of the disconnected disk, no success.  
pulled it out and plugged it back in again, still not detected..  
tried all sorts of combinations of reinit attach detach etc with  
atacontrol... Finnaly I gave up and rebooted the box and now it's  
rebuilding again...
Does anyone have any clue why this is happening? Okay its better than  
before, no crashing.. but loosing one drive in a gmirror and having  
to reboot to fix it is not good.

Thanks
