Our 2ndry DC, which is on a W2K8R2 Mirrored software raid has lost it's sync, and disk management displays the failed redundancy error

enter image description here

How do I know which of the disks has failed? (beside to try and replace one - and see if it loads and syncs)

On the device manager, under disks I see both disks, one of them has an icon of: Disable, while the other doesn't

enter image description here

Event log displays an event id 7 - bad block on Hard disk DR0

enter image description here

The thing is that looking in device manager, both disks are located in '0' location, which is bizzare
