Rebuilding a Storage Space - Two way mirror

Question

I received a message that one of my two identical 3TB hard drives in a simple two-way mirror Storage Spaces in Windows 10 had stopped working.

I have identified which one of the two it is. I removed the disk from the computer and inserted it into another machine. It is perfectly fine. Data all there.

I have now replaced it in the original machine, checked the cables, etc, and it's detected in BIOS and device manager. It isn't giving me a "Lost Communication" error. I cannot get it to resync and approve the drive. I have tried:

PS C:\WINDOWS\system32> Get-VirtualDisk

After that I tried:

PS C:\WINDOWS\system32> Reset-PhysicalDisk

And nothing changed.

Have looked at this article hodkins.io, however it doesn't work on account of Windows demanding a fresh drive before removing the old one.

Is there any way to rebuild this mess without a new drive? I could probably get one but I would have to overpay for it or it will take a couple months. One should be able to resync 2 perfectly good drives with no issue...
