Use 10TB RAID 1 Mirroring With ReadyNAS 212 Two Bay.
ReadyNAS 212 Two bay diskless
ReadyNAS OS 6.9.5 ARM
Two Western Digital 10TB RED NAS SATA 3.5 Inch hard disk drives
System does not recognize disk in bay 2 (LED does not light, readycloud shows a blank next to the graphic for bay 1 disk).
If I put a one terabyte disk in bay 2, then the LED lights up and there are entries for both bays in the readycloud interface.
The information at http://www.downloads.netgear.com/files/GDC/datasheet/en/RN212-RN214.pdf shows that the max for RN212 is 12TB, two 6TB disks.
I want to run RAID 1 mirroring. Will RAID 1 work for dual 10TB disks? Should I configure X-RAID or Flex-RAID, or is there a RAID 1 config?
Thanks for your consideration.
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.

Hi geishaslave, to exclude the obvious I would make sure that the concerned 10TB disk is not dead. Could you try using it with a PC, for example?
Kind regards
Thanks.
Yes, both 10TB WDC RED drives work when connected to SATA ports on a PC. I have also swapped them between bays 1 and 2 in the RN212 and both are recognized, but only in bay 1.

XRAID is fine, as it will use RAID-1 with two disks of the same size. FlexRAID is also ok (and if you use it, you explicitly specify RAID-1). However XRAID is simpler.

Netgear datasheets use the max size on the HCL when they are published, and they generally don't revise them just because a larger disk is qualified. The current technical specs quote 24 TB based on 12 TB disks. https://www.netgear.com/home/products/connected-storage/RN212.aspx#tab-techspecs

I suggest using the admin UI directly for this, not ReadyCloud (that is, use https://nas-ip-address/admin or https://nas-host-name/admin, using the actual IP address or host name). I also recommend installing RAIDar on a PC - https://kb.netgear.com/20684/ReadyNAS-Downloads

Check your warranty status at my.netgear.com. If you are covered then request an RMA via my.netgear.com.
I suspect that your issue is power-related. So if you aren't covered by the warranty, you could do a risk-buy of a replacement power adapter.
Thanks.
Since you mention POWER I suspect this may be that 3.3V PWDIS issue with SATA power pin 3 as described in the PDF at the following URL:
I will receive some polyimide (Kapton) tape tomorrow then cover pin 3 with a tiny sliver.
Again, my RN212 has no issues powering up other drives with SATA connectors. I tried 2.5 and 3.5 inch units, including an SSD, both bays 1 and 2 filled at the same time with full success. But then after I successfully mounted other SATA drives in the ReadyNAS 212, neither 10TB RED drives would spin up (no lights for LEDs 1 and 2) when before LED 1 would illuminate.
For the record, the 10TB drives I am using are from Western Digital Easystore USB 3 enclosures. They were on sale at BestBuy for $169.00 and if ordered for store pickup via customer account. The drives contain EMAZ in the model number. They are RED NAS helium filled variety, but with a white label. Made in Thailand with 256MB cache.

I'm impressed! The cheapest 10TB drive you can get in Germany (heise preisvergleich on 20190224 1500CET) is a Toshiba X300 (HDWR11AEZSTA) for €275, which is >US$310 depending on the exchange rate you might apply. I wonder, what has been sold to you in the end while being claimed to be a 10TB hdd.
