ReadyNas Duo V2 disk change
Hi. - I have 1GB WD green installed in my readynas duo v2 and everything has been working well. As the disks are nearing capacity, I bought 2 WD EFRX 3TB disk (I checked and it is compatible with the ...
What firmware is your NAS running? Many v1 owners mistakenly think they have a v2 - the labeling is confusing. This matters because the v1s are limited to 2 TB drives.
Duos running 4.1.x firmware are v1 models (not v2). Duos running 5.3.x systems are v2s.
If you are in fact running 5.3.x, The next step is to test the disk - best done by connecting it to a Windows PC with SATA or a USB adapter/dock. Then test it with WD's Lifeguard program.
You could remove the new disk, and hot-insert the other one, and see if it comes up normally.
If you do need to exchange the new disks, I suggest making sure you get the EFRX model, and not the newer EFAX. The EFAX is an SMR disk - it might be ok, but there are some drawbacks to SMR. You could also go with the corresponding Seagate Ironwolf models. Note the NAS HCL hasn't been updated in a long time, so it's not as useful as it once was.
- Hi Stephen - yes my firmware is 4.1 something but when I looked at the back of my readynas, the label did say v2.
I did what I said to Marc before and now the capacity is showing only 700GB. I tried to insert the old drive back and now doing initialization. will wait until it is finished.

The 700 GB size is because the NAS can't handle disks over 2 TB. It doesn't use GPT formatting, and the math it uses for sizes overflows with larger disks. So 700 GB is all you'll get if you stick with your 3 TB drives.
If I were in your shoes I'd exchange the disks for WD20EFRX (not EFAX) or 2 TB Ironwolf drives.
To be more complete:
A Duo v1
- says "Duo" on the front panel
- runs 4.1.x firmware
- often has a label that says v2 or even v3 on the back
A Duo v2
- says "Duo v2" on the front panel
- runs 5.3.x firmware
- often has a part number label with -200XXX on the back.
- Hi stephen - I finally got a replacement but unknowingly got given the EFAX version. Will this be bad or I need to ask for an exchange again? I looked at the HCL and the EFAX is nowhere there, so I am worried if I open it - I will end up not able to exchange them. I am already installing the 3TB version on my PC as data disk - so dont want another 2TB there.
