I have a software RAID1 on a machine that had a BSOD. After it resynched, I noticed that there was "failed redundancy" error message. After searching around, I read that I needed to "Reactivate disks". However, I must have done this incorrectly--I reactivated  both disks in the RAID. Now, it appears that there are 4 disks in the RAID with 2 disk missing, and it still says "Failed Redundancy".

What do I need to do to fix this issue?

I removed the missing and foreign disks, and this is where I'm at now:

They now appear as separate logical volumes with two different drive letters instead of a single RAID1. When I right-click on the individual volumes, the options for "add mirror" and "reactivate volume" are grayed out. When I right-click on the disk, the option to "Convert to basic disk" is grayed out.

This is what it looks when both start online, and I take one of the disks offline:

This is what it looks like when both start offline, and I take one online:

As you can see, Windows isn't really treating them as completely independent disks as the state of the disks/volumes are different depending on whether both start from online or both start from offline.

And for thoroughness, this is what it looks like when both are offline:

I ended up deleting one of the disks and recreating the mirror. I have no idea how the mirror got split into two independent disks, but there doesn't seem to be anyway to bring them back together.
