Use 10TB RAID 1 Mirroring With ReadyNAS 212 Two Bay.

I think I figured it out.

Probably voids the warranty however :-(

Solution was to replace the 3V CR2032 battery on the cpu board. I don't know if resetting the BIOS or installing a fresh battery was the fix. The original battery had a voltage of 3.07 using my multimeter. I had a new battery on hand, and the fresh one had a V of 3.27. The experiment to do would be to put the original 3.07V batt back in and see what happens.

Had to remove the circuit boards from inside the case since I could not get to the battery otherwise. I removed the sides of the case. There are three boards and the fan assembly. The fan is plugged into what appears to be a system board. The system board has a heat sink over the quad core ARM cpu, and the mount holding the 3V battery. The two SATA data/power connectors are mounted on a small board plugged into a connector on the system board, parallel to the fan assembly. The third board has the DC in, 2x network jacks, 2x USB3, and single eSATA ports, also plugged into the system board, parallel to the fan assembly. I removed the fan assembly, then the SATA board, then the DC power/external connect board, then the system board. I popped out the battery then replaced it. Assembly was in reverse order:  system board --> connector board --> SATA deck --> fan assembly. I put the sides back on. Connected the AC adapter then pressed the power button. After the LEDs stopped blinking, both LEDs for for 1 and 2 were lit and steady. I power cycled to confirm all was repeatable. I was unable to log into the admin page, so I did boot menu to the reset to factory default.
