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.
It feels like the safest way is to take a 5TB USB disk, make a backup.
Check the backup so "everything" is included
move the disks to a 214.
format and redo.
Unless everything is included in the backup, I can try to migrate the information

That would only work if the backup button was already provisioned to back up the full NAS (since you have no network interface you won't be able to set that up now). If no jobs were set up for the backup button, then pressing it does nothing.
I would back up the system first if you can. But I wouldn't start over with a factory default on the new NAS unless that was actually needed. So I'd look in the log zip file first, and see if there any disk or btrfs errors in system.log or kernel.log. I'd also look at the SMART settings in disk_info.log If I saw something, then I probably would start over.
Note that you can make a backup after you migrate to the RN214 (and you should certainly put a backup plan in place).
