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 power supply and then re-connected it, but same result. Not even one single light is visible.
What can I do?
If the unit cannot work anymore, how can I backup the two disks outside the unit?
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.
You are quite right. I have just used a voltage-tester to check the output and it shows nothing - but it is the same result with a similar and working power supply, unfortunately.
I will look for a power supply replacement and then hope it wil
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 ordered a compatible power supply but still I need to know whether there should be plus (+) or minus (-) on the outside of the 12 V plug?
Look at the label on the plug or the existing adapter.
These usually have the vital statistics. All they miss is the dimensions of the tip.
Great! It seems to be plus (+) inside and minus (-) on the outside.
Here's a pic of the PS from my Duo V1.
Center is +. PS is 60W.

That's a good start. I'd start with the suggestion from StephenB that you search for something that claims compatibility with your Netgear device. If you can't find an exact match, anything that says it supports the whole range should work.
Netgear occasionally comes up with something odd, but mostly it sticks to transformers that cover a raft of devices.
Check the onboard CMOS battery.
