ReadyNas 212 HELP needed
Hello all, I have a Readynas 212 and I need help after making many errors. I currently have 2x 4TB drives. Drive #1 is older and had data already. I turned from JBOD to RAID1 by moving for X-RAID...

is there anything that can be done to try to recover the data on either 4TB #1 or #2?
First, don't bother with tailed drive. Boot up the system with only the 4 TB drive in place.
If you are still using password as the NAS admin password, then change that to something. Then double-check that ssh is still enabled in system->settings->services->ssh.
You can then download WinSCP ( https://winscp.net/eng/index.php ). That supports a protocol called SFTP. Set up a connection that uses that protocol.
Use the IP address of your Nas (not the one in the screen shot).
After you connect, the right pane should look something like this:
Somewhere in that list you should see your DSK-4TB folder. Navigate into it, and see if your shares are listed. If they are, you can copy them to a disk on the PC.

Should l eliminate/destroy that "data" volume that is showing up there with 0 for Data and 0 for Free Space?
No. Doing that will make it even more difficult to recover.

Then saw that Drive #2 is degraded,
Drives are never degraded. Volumes are degraded. Shuffling around drives might have made recovery more difficult.
FWIW, if you were running XRAID before, all you needed to do was hot-insert the new drive.

I've downloaded the logs
I can take a look if you like. Upload the full log zip to cloud storage (dropbox, google drive, etc), and send me a PM (private message) with a link. Make sure the permissions are set so anyone with the link can download. You send a PM using the envelope link in the upper right of the forum page.
Don't post the link publicly, there is some privacy leakage when you do that.
Have you left out some steps? I think you may have done this:
Started with a 6TB drive in bay 1 and 4TB drive in bay 2 as separate JBOD volumes. You then powered down and removed the 6TB before doing what you've listed. But6 how you had two volumes and were still in XRAID mode has me questioning this. At any rate, the 6TB is involved somehow, and you need to include it in your description.
NAS are not designed to be drive bays in which you can swap drives back and forth. So if I'm right, then you have very much confused the OS. It looks like it marked the original 4TB as RAID1 but couldn't add the other to that RAID, thus it is degraded. I've never done this, so i can't be sure, but I suspect the problem is that the OS still reserved bay 1 for the 6TB drive.
It also appears to me that your 6TB was the primary volume and the 4TB the secondary, which made the situation even worse by booting without the primary drive.
It's unclear to me why you wanted to go to RAID1 when you wouldn't have room for all three drives. Was this an attempt to create a "backup"?
If I'm right, then I believe that you've only confused the GUI and you can get to your files via SSH.
You can probably get everything back and get the GUI to recognize everything by booting with the two original drives. But I'd do so in read-only mode first (via the reset button menu) just in case that doesn't work. The 4TB volume will still show as degraded, but I think you'll get access back. If this all works, once you back up the data and feel comfortable booting in read/write mode, I can tell you how can use SSH to tell the NAS that the 4TB is actually JBOD so it doesn't complain about the volume being degraded.
