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.

may that be possible even when deep formatting on the disk has been made recently??
MAC addresses are only available on network equipment, is it not??
It wouldn't be using a MAC address (since as you say that doesn't apply to disks).
But it does have a path name for the destination of the backup - which can include the volume name. So you might want to match the volume name and folders that are on the 1 TB drive, and see if that helps.

It still works now with the backup to the 1TB disk.. at best, it continues and downloads the continuing (and not the first TB'n again)
But I'll see that tomorrow..
Almost certainly it will download the first TB again. Personally I think you should be switching to R-Studio - you already have it, and it seems to me that you aren't making any headway with the damaged hardware.

the Seagate disk has two USB charging plates on it .. it is a possibility that it acts as a USB hub .. but then it is strange that the disk is visible but not mountable.. but it may be a security lock in the NAS that USB hard disks may not be mounted with hubs in between..?
There's no security lock. But a built-in hub might be getting in the way.

if it does a "smart" scan then it gets the disk type and serial number .. now i don't know if it works over USB ..
I tried to rename 6TB to the same name as 1TB disk ..
but the same results as before, "USB disk connect"
but no light on the backupp button..
holding the button in 6sec so it says "USB mount faild"
I only got the first TB'n, again on the little HD..
i am system designer and not "technician" ..i have technician's to
solve the functions and requirements that i set on the systems i build up ..
If the technician cannot handleit, then it's the wrong technician ..
Of course I took it for granted that, just move the disks to new hardware, especially if the raid is in good condition ..
Of course I took for granted that it could possibly require a restructuring of the raid, in order to fit the new system. but with
preserved data

Well, now, "this" solution begins to take equivalent energy .. almost more a matter of principle
..and i have no extra computer right now for a practical test bench and raid dumping..
