Hi all, I have just installed windows 8.1 on my tower PC.

The previous set up has 2 software RAID mirrors set up using the Win 7 functionality. Upon loading Win 8.1 the 4 drives (2x mirrors) are recognized by Computer Management correctly, but show up as failed. Trying to "Reactivate" these does nothing other than have Win 8.1 show me the "thinking" circle for a few seconds then back to square 1.

Below is a screen shot of Computer Management.
