After booting up my MP this morning it would not allow me to log in and came up with an error message. I shut it down and started back up which worked and I was able to log in. When I logged in the RAID Utility came up with warning about a possible drive failure (I am at work and will post the exact message when I get home). I checked the Disk Utility and it said the RAID 0 disc (which are disc 2 and 3) was "Viable (Good)" while all the other disc said they were "Good". Is this normal?
