How to recover/read data on 4 X-Raid2 disks
My Readynas NV+ (RND4000) is dead. Even with a new power supply he's not starting. I need to recover all the data (my whole life on photo's and music is stored there). How can I do this? I had 4 1TB disks in X-RAID2. Can I recover this in another Readynas system? Or when I can find a second one. Or is there another solution to read the data on the disks?
A lot of supplies have eliminated the white wire, so you have an unused pin across from the grey one. Try popping out the blue pin or cutting the blue wire and see if your NAS will then power up with no drives. Without doing that, the -12V is shorted to the +12V, which will typically cause the power supply to not power up. But it not powering up is what causes it to do no damage when you didn't remove the -12V.
I don't know what I was thinking when I said the +4 has two 12V wires. You are correct, it has but one. But you can generally get enough power with just two, so put that yellow one from the +4 in place of the blue or in the currently empty spot across from the grey. But if the CPU connector cable is long enough, also putting one of those yellow ones in the other position is best.

If the disks are ok, then RAID recovery software should work.
You'd need to connect all the disks to a Windows PC (probably requiring a suitable USB enclosure), and then you could try R-Studio (getting the license that includes ext and raid-5). There are other options for recovery software.
You'll also need enough disk space to copy off the data.

What happens when you remove the disks (label them by slot as you take them out), and start up the NAS diskless?
Are you seeing a "no disks" status on the LCD display?
Even when I remove all the disks, the NAS can't start. He's completly dead. I replaced already the power, I tried to bypass the power button, nothing works. He's dead since a few power outages in our street in the same week.
Does R-Studio recognize X-Raid2? It's something specific for Negear.

The NV+ (like all 4.1.x systerms) would have X-RAID. The NVX/Pro/Ultra NAS (4.2.x firmware) would have X-RAID2. Either way, XRAID is just a management layer Netgear built on top of ordinary RAID. R-Studio (and other RAID recovery tools) can recover the data.
Of course we are assuming that whatever triggered the NAS failure didn't also result in damaged disks.
