Help determing failed drive on 3ware card

[Bladestorm]

I'm trying to help someone over email figure out which of the two drives in a mirrored array is the bad one. Their controlled by a 3ware 9650SE-2LP in a server chassis. I know that Port 0 is the drive on the left, and Port 1 is on the right when looking at the front of the server, but I don't know if this screenshot is telling me that 0 is good or bad?
