did my readynas duo v2 finally die?
i got this used in 2011 from an acquaintance. Since I bought 2 new drives (WD red) in 2012 since one drive went kaput and I wanted to keep the same model drives. I had issues before where power outag...

I reformatted my 3.5" drive and it's usable in windows 11. But then i plug it into the NAS, i still get the same beeps. Time to call it quits and declare it dead?
I still am wondering if it is the disk. The NAS has no speaker, so it actually can't beep - all it can do is flash the LEDs. If you are hearing beeps, they are coming from the disk - which is not a good sign. WD says to replace the disk if you hear them. But this could also indicate a power problem, especially if you don't hear them when they are connected to the PC. Still, the very slow formatting time in Windows suggests the disk isn't very healthy.
So I think the three possible causes remain on the table:
- failed disk
- power issue with the adapter
- failed chassis
But I think it does make sense to move on.
Personally, I am going to run my own Duo v1 (and NV+) as long as they work. But I won't spend much (if anything) to fix them when they eventually fail. My primary storage and backups are hosted on newer, faster NAS, these two are only used as secondary backups.
That said, you could alternatively do a risk buy of a compatible power adapter, and/or a replacement disk. Total US cost would be around $125 (assuming a 2 TB purchase). The disk could be used in the new NAS if this fails, so the risk is only the cost of the power adapter.
It looks like you actually have the original Duo - called a v1 here.
The original duo
- says "ReadyNAS Duo" on the front panel
- runs 4.1.x firmware
The v2
- says "ReadyNAS Duo v2" on the front panel
- runs 5.3.x firmware.
There are other labels on the original Duo that might include v2 - those indicate minor hardware revisions, and create confusion when identifying the platform. So ignore any other labels.
The LED patterns are
LED blink behavior for 2 disk systems is three quick blinks of all disk LEDs and the backup LED, followed by an 1s delay, followed by a number of slow blinks. The number of slow blinks will be the error code.
Current error codes:
1 - Vendor mismatch
2 - No disks detected
3 - Bad contents on root partition of disks
4 - Flash error
5 - Unsupported RAID configuration
So this sounds like the NAS is not detecting the disks. I suggest powering down, and connecting them to a Windows PC (using SATA or a USB adapter/dock). Then test them with WD's dashboard software.
If you still have 2 disks in the NAS, then label them by slot as you remove them.

No need. The WD20EFRX is no longer manufactured, so anything you find online would be old inventory. The replacements are the WD20EFPX and the WD20EFZX. Both of these are branded as WD Red Plus. The 2 TB Seagate Ironwolf (ST2000VN003) will also work. You can use any of these three options in your NAS (and they don't need to match).
Avoid the WD Red (WD20EFAX), as it uses SMR (Shingled Magnetic Recording), which doesn't work that well in RAID arrays. FWIW, most desktop-class 2 TB drives are now SMR, and should also be avoided.
Note the original Duo is limited to 2 TB or smaller drives. The v2 can handle larger ones.
