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...

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.

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.
- Old IT saying: "If you only have one copy of something, you must not think it's important."
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?

It works to use the front USB and start a backup.
I have another 1TB disk that function well, now it has backupping a few hours,
then we'll see if I managed to trick it into taking the rest, and not just the first TB'n (again).. - SinegrafJul 16, 2019Guide
it says in the window that it finds the USB disk ..(with 6TB on all USB inputs)
but the Backup button does not light up.
The backup button does not respond to a normal button press.
at long 6sec press it says that it cannot mount the 'drive' (do not remember what exactly it was, but it was 'mount' it couldn't) - StephenBJul 16, 2019Guru - Experienced User
Sounds like the backup job was configured to go to a particular disk.

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??
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..?
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.. - SandsharkJul 16, 2019Sensei - Experienced User
I am quite certain about Netgear not providing parts or out-of-warranty hardware repair on the NAS product line. They do provide paid technical support, including data recovery and transfer assistance, so long as you are the orignal purchaser.
If the NAS is just backup, I don't quite understand all the consternation. Just buy a new NAS and do the backups again. Is it that much more trouble than moving the contents of the drives to an intermediate storage location so you can put it on another NAS?
My understanding of the transfer process is that they remotely mount the volume for you so you can transfer the files to a local drive. Thus, you should not need to be worried about anybody seeing your data. I suppose they have the capability, but it would be a business practice that could get them in serious trouble to actually do so.

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.

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.

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 tosolve 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 dataNow I don't know if it's the system designer or the technician who didn't do the task- 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.
Well, now, "this" solution begins to take equivalent energy .. almost more a matter of principle

"Okay" now I have RStudio started.. My first attempt at scaning failed..
and "auto" on the RAID parameters did not work..
-so i am humble and ask .. the basic..
The disk arrangement in NV + v2 is from Left to Right?
Is it standard RAID5? (not 5E, 5EE)
Block order= Left Synchronous
Block size= 64KB
Anyone who is sure that "Parity delay" is not used in any way?
-as I mentioned, I had a brain haemorrhage .. therefore I normally do NOT do this today..
So, I BELIEVE that all the disks were mounted and created the volume created on the disks.. we can assume that this is the case..
worst case, three disks and extended the system with the fourth when the system was originally created for three..
would then the RAID still be "standard RAID5" - StephenBJul 20, 2019Guru - Experienced User
Though your parameters look reasonable, I don't know the underlying RAID parameters (and don't own a v2 NAS). I am thinking that you might want to try a different free tool that might correctly detect them: http://www.freeraidrecovery.com/?s=rd Netgear ( JohnCM_S ) might also chime in and tell you what they are.
It'd probably be smart to clone all the drives if you can (since they are the only copy of the data).

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?

I need to study mdadm... :)
it found some mdadm blocks, on the "volyme" but they seem "locked" ..
Thx, Then I have a guide on how it might be possible to open.. - SinegrafJul 23, 2019Guide
Short description, for RStudio
forget to try to create traditional "virtual" RAID5 and similar..
concentrate on opening the mdadm volyme, and let RStudio scan the entire volume, The information on how it is created will be found when scanning.. for me, the scan of 8TB took 25 hours
when you choose recover, turn off exporting "hidden / extended attribute's"
expect 15-20 hours per TB
Great tips for those with NAS as the guarantee gone out ;) - StephenBJul 23, 2019Guru - Experienced User
