Readynas DUO disk issue - blinkng LEDs
I have a Readynas Duo (V2 I think). Two 1TB seagate disks, it has worked well for about 11 years. Recently one disk showed an error, so I bought new disks which are 2TB. New disks (brand new - unu...
Thanks for the reply
Firmware is latest that there was RAIDiator 4.1.16 [1.00a043] So this suggests a V1 even though label says V2.
What I do not understand is why the new disks worked fine after hot swap, initialisation and RAID sync, the system showed fully redundant, but only give failure indication on NAS restart ?
Could it be that despite being on HCL they are not fully compatible?
I do have a full backup on an external disk which has been copied elsewhere, so my data are safe
I have just found an ebay seller with a new unused 1TB disk same as are in there, so I will try that.
I am considering buying an RN422, I hope the new disks will work with that.
The NAS also no longer shows up as a network drive on my windows PCs, I believe that this is due to Windows 10 update changes. I have tried the various solutions I see posted, but no luck. I can connect using a saved shortcut, whch works sometimes!

I mentioned the labeling above. Netgear also uses "V2", "V3" in labels to identify hardware revisions (usually minor component changes).
So you have hardware revesion 2 of the original (v1) Duo. Not the Duo v2.
Netgear made a huge mistake when they branded the Duo v2 and NV+ v2, and many, many owners of the original Duo and NV+ mistakenly think they have the v2 platforms.

The HCL for that model hasn't been updated in many years. But any 2 TB enterprise disk will work, as well as WD Red Plus or Seagate Ironwolf disks. Avoid WD Reds as they are SMR. Duo has a max disk size of 2 TB. My own Duo has a WD20EFRX and a Seagate ST32000542AS.
Any enterprise or CMR NAS-purposed drive will with the RN422 btw - though it can handle much larger disks (16 TB drives on on its HCL). The 18 TB SATA drives coming on the market would work too, though they are still extremely expensive.

I always test new disks before I use them - using the long test and the full erase disk/write zero tests I suggested above. I have had new disks fail those tests (sometimes failing one and not the other). Note disks can be mishandled during shipment.
So I'd start with the assumption one or perhaps both of the disks failed - and test the disks to see if that's the case.
