Suddenly one night my unit just stopped - cannot start again
Reg.: RND2000v2 (ReadyNAS Duo v2) – Diskless A couple of days ago my unit stopped working, it powered off somehow. Now I cannot start it again using the power button. I have tried taking out the pow...
I managed to backup both my 2 TB disks although it was a huge job taking a couple of days. I merged the data from the disks to prepare it for my new NAS Server which will be delivered later this week.
There is a good chance it's the power supply that's gone bad. You can test it's output, but that's not really a very effective test without a load. A risk buy of a replacement supply is something you should consider.
There are methods of recovering data from the unit, but you cannot do so directly from Windows. How you go about that depends on whether or not you have a "real" V2. Netgear used a "v2" designation on a sticker with some units that had a simple hardware difference but are still referred to here as a V1. A "real" V2 is an entirely different machine, labeled as a V2 on the front of the unit, having an RND2000-200 (as opposed to -100) part number, and running OS version 5.x (as opposed to 4.1.x). So if you want information on how to recover, you need to confirm your NAS really is a V2 or if it's actually a V1.
This is my model: RND2000v1 (ReadyNAS Duo v1) - although on the bottom a label says V2.
So, two questions:
How can I backup my disks or at least the main one? (the other disk is the first mirrored).
What is the best replacement of my present hardware bought October 2010?

(a) Do a risk-buy of a compatible power brick, and then see if you can boot the NAS.
(b) Install R-linux on a Windows PC, and connect the main disk of the NAS to the PC (either SATA or with a USB adapter/dock). Then offload the data with R-Linux.
It is also possible to mount the main disk on a linux PC manually.
Note that the "main disk" is usually disk 1, but there are some scenarios where it ends up as disk 2. So if your files don't show up with R-Linux, try the other disk.

If I were looking for a replacement myself, I'd be looking first at
- Asustor
- QNAP
- Synology
(listed alphabetically). I've not owned them, so this is not a recommendation - just a starting point.
I'd also be looking at multi-bay enclosures (USB-C, Thunderbolt, or perhaps Mini-SAS). With the size of current drives, I don't really need RAID, and I already have an always-on desktop that I use as an application server.
I have tested my NAS with a proper power supply replacement - but it will not boot.
Therefore I will take out the disks and try to back them up. Why do you recommend using Linux? Why can I not just use Windows 10 / 11?
Is it possible to back up the disks as readable data?

I didn't. I recommended this:
(b) Install R-linux on a Windows PC, and connect the main disk of the NAS to the PC (either SATA or with a USB adapter/dock). Then offload the data with R-Linux.
This page will open to the Linux download, but there is a "For Windows" tab in the upper right.
Keep in mind that the NAS is using a file system that Windows doesn't use. The windows disk manager will see the drives, but you can't mount them using ordinary tools. If the main disk is ok, then R-Linux should find the files, and let you copy them.

That is what R-Linux would let you do.

Does it power up, but not fully boot? Or does it not power up at all?
If it powers up, but doesn't boot, there might be some damage to the file system.
