Can't Access Data on RAID1 Volume with Missing HDD

[Ponteaus]

I just received a diskless NAS for Christmas and am attempting to migrate the disks in my gaming tower to this new system. The gaming tower has 1x128GB SSD, 2x500GB HDD, and 2X4TB HDD. C: colume is on the SSD and will remain. F: volume (files) is on the HDDs and needs to migrate. Each pair of HDDs is in a RAID1 configuration.

My migration plan was:

1. Remove one HDD from each RAID pair and install in NAS

2. Copy data from tower to NAS over network (assuming NAS wouldn't recognize data on disks)

3. Remove second HDD from each pair and install in NAS

4. Switch NAS to RAID

However, upon removing the first 4TB disk, Intel Rapid Storage Technology program immediately marked this RAID volume as failed (huh? It's RAID1, the data's still on the remaining disk), and Win10 will no longer allow me access to F: (makes sense since Intel is claiming the underlying RAID volume is failed).

To attempt recovery, I removed the HDD from the NAS and reinstalled it in the tower (same SATA port as before). RST is marking it as a 0GB drive and refusing to do anything with it. Anything I do to try and create a volume or delete a volume or whatever warns that data on the disk will be lost. I've tried this from both the Win10 program version of RST and the interrupt boot-up version of RST. How do I get this software to realize there's good data on the remaining drive?

My data is backed up to Backblaze, so data loss isn't a concern, but I don't want to download a TB of backup data just to fix this. The data is there and good!
