no network after lightning strike
No network link no network activity lights USB backup works So disks and RAID systems work (Raid5 4x3TB now 4,2/8,1T free) So a simple solution could be to move the disks to a new 4Bay Read...

NV + v2 RAID had the latest available software for that model ..
Now I don't know if it meant X-RAID gibbrich ..
If it has X-RAID, it is probably the "writing order" that is special
the writing order can be affected by "parity delay"
Someone who knows if it is 100% normal (RAID5 standard) or a separate secret rule?Your NAS uses software RAID (mdadm). XRAID is layered on top of mdadm - it manages RAID groups for you automatically (which allows for expansion of the array). But underneath it is just mdadm - there is nothing proprietary about the on-disk structures.
FWIW, it sounds like R-studio isn't finding the mdadm superblock. It's possible that the superblock was corrupted when the lightning stuck. Though I'd have expected an error on the LCD panel if that were the case.
As I said earlier, I don't know what parameters are used when the array is created.

can ReclaiMe manage NETGEAR NAS?
Folks have used it for OS-6 ReadyNAS (which uses the BTRFS file system). I don't recall seeing it used for OS-5, but it likely would work.
The free tool I pointed you too will only find the RAID parameters. The paid version is needed to recover files. However, you can alternatively download the paid version, and see if it can recovery anything before you actually purchase it.
You could also contact R-Studio support, they might know the parameters used by your NV+ v2.
Netgear offers no parts or out-of-warranty service. They do offer a paid service to assist you in moving your data off your drives so you can put it on a replacement Netgear NAS. So, that's one reason for buying the 524X. You do have to hope the drives and the data on them are still OK, but your steps to date seem to indicate they probably are.
A ReadyNAS (or any other RAID storage) adds redundancy to your data, which is mainly for continued access through a drive failure, not backup. If the NAS is primary storage, not already backup, then it needs a backup. Old IT saying: "If you only have one copy of something, you must not think it's important."
You were a bit unlucky with how long your NAS lasted. I have several that are still going after many years. But it is still little more than a specialized Linux PC, so one should expect it to fail at some point. Whether a lightning arresting system would have helped, who knows. That bolt just traveled miles in air, so why would a little MOV or similar device stop it now?
If you can get someone to certify it was a lighting strike, and you have other damage where the total exceeds your deductable, most homeowner's and renter's insurance does cover you. Of course, it covers the device, not the data. At least I doubt it covers data recovery.
There is a 5V-level serial port on the NAS. Information on using it can be found on the internet, though the pin-put of the various units isn't consistent. The problem is, I don't know if you can log into the serial port if SSH was not already enabled. If you are adept enough at Linux, you could use the serial port interface to type commands to back up your NAS to a USB drive.
One last thing: Have you tried connecting the NAS directly to the Ethernat port of a computer? I had a NAS that was damaged by a power surge (I bought it that way for parts) and it would not work on a "green" Ethernet switch or router, but it would work at 100Kbps on a stronger system, such as directly on a computer.

I hope you are wrong! if the company does not provide service and repairs to things beyond warranty (Of course I had thought to pay for it ;)
unfortunately there are parts of the data that I cannot allow others to have access to .. Now I know that the disks work and that the raid is intact, so it is easy to copy the data for approved companies.

this is a inhouse "backup NAS" for our "work NAS" which also has Backblase B2B.
Data in one place (no matter how many backups) is not safe.
My wife's computer was completely destroyed at the same time, she is lucky when the information is then on the "working NAS" which also adds a backup on the broken "backup NAS". Now a backup is also located on a server on another continent .. so I can handle the house peace :)
the insurance company pays for the equipment, but not for the data or to get it back
I just got a Desktop Storage Seagate 6TB USB "disk" who use USB3 and USB2
the disk has NTFS and the NAS finds the disk and connect, but cant mount the drive... so I can't try to make a USB backup to the disk.. the system can handle 5.54TB disk?
