Disk 1 doesn't look like it has a volume (partition). Have you tried to create partition and then create your mirror?

Hi there
I believe to use mirror / striping in RAID 1 configuration on Windows you need to use Storage spaces - so set the 2 HDD's into a storage space and then you can adjust striping / mirroring.

I don't use software raid 1 anymore. Instead setup Storage Spaces (Two-way mirror)
