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 Nas).
I installed the first disk with the new drive - leaving the second intact with 1TB disk. The machine booted up but failed to rsync saying the new drive was dead.
Any way I can resolve this issue? I havent tried installing the second one yet afraid that it is going to be the same result again.
Regards
Michael

You can remove the drive you added and test it on a PC to confirm if it really is a dead drive. Also, replacing it with the 2nd drive will also confirm if the NAS has the issue.
If the 2nd drive was successfully added then there might be an issue with the 1st drive.

Regards- Hi Marc - thanks for the reply. I just took out all the disks and insert the new 3TB disk in. It seems the system is successfully installing in the disk, which means the disk wasnt broken.
But how do I go on after this? Will this 3TB disk be able to shrink into 1TB again?
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.
