Added Drive, changed from JBOD to Raid 1, can I change it back?
I had a ReadyNAS 212, with one 4tb drive... Netgeat site says to add more storage, just add another drive to bay 2. When I added another 4 tb drive, it changed me from JBOD to RAID 1. I don't w...

Unfortunately once it does that you need to start over - either with a factory reset, or switch to flexraid and destroy the volume. Both are destructive, so you might as well back up the data, pull one drive, and then do the reset.
After that, switch to flexraid on the volume page, and then insert the second disk. You'll be able to create a second 4 TB volume.
Then of course recreate the shares, and restore the data.
geez.. thats a bummer. I have almost 1tb ripped and saved, with about 4 more to go. I have no place to back up 1tb. It would have nice if this were explained somewhere - about changing to flexraid to preserve the JBOD when I added the new drive. It happened automotically - no choice or notification that it was changing to RAID 1.
What would happen if I removed the drive? Would it revert back to JBOD? if it did, I could them change to flexraid and add the drive, which I could reformat and clean the duplicated data.

The volume would become degraded. You'd be able to switch to flexraid, but you wouldn't be able to change to jbod.
However, you would still have access to your data, so you could temporarily reformat the removed drive, and copy the data off. Then do a reset, switch to flexraid, reconfigure the NAS shares, and restore the data.

Then at some point you will lose your data. After you get through this, you should put a backup plan in place (USB drives are one way that is pretty affordable).
As I understand it, FlexRaid like like JBOD, but safer (according to Wiki.flexraid.com).
So, If I remove Drive 2. Switch to Flex RAID, re-add the Drive 2 and reformat it, I'll be able to see all 8tb as a single volume, just like JBOD, without losing any files or settings, right?
As for back up, I'll pick-up a seagate or WD 2tb at Best Buy to back up my current media files just incase.
This is my first NAS, but I've been building my own PC's since the late 80's and have yet to have a drive fail. But then, I've always had a back up in place. I'm sure if I didn't, i would have had a failure.
