ReadyNas Ultra 4 RNDU4000 - Could not properly exctract
So I have been using my Readynas ultra 4 for a long time now, and finally it was time to upgrade the disks. I found that the 4TB WD Red was supported for my device, so purchased 4 of these, and swa...
Finally!
After scratching my head for a very long time, attempting 5 different USB's of different sizes and ages i finally came to the conclusing that the usbrecovery.exe program shouldn't pick the .html file as the image, so i tried deleting that and adding the files to the USB devices again... On the 7th or 8th try one of them finally booted! Imagine my surprise when my NAS suddenly turned itself off!
Got the old RAIDiator firmware up and running, upgraded to OS6, swapped out the old 2TB disk for the new 4x 4TB disks and did a factory reset to OS6 and updated to the newest OS6 version.
Everything seems fine now, and its currently resyncing data.
Thanks for the help all, seems persistance was key to solving this problem after all. Almost gave up on the entire box to go for a DIY NAS project with my old PC, now im glad i tried and tried and tried untill the issue was resolved!

However when i swapped in the last disk it seems it couldn't expand my volume any further. After some researching i concluded that i hit some kind of max expansion for a volume.
There are two expansion limits with 4.2.x firmware.
- A volume cannot be expanded over 16 TiB
- A volume cannot grow more than 8 TiB from it's starting size
4x4TB would give you a 12 TB volume (10.9 TiB), so the first limit doesn't affect your system. But the second one could (and likely you did hit it).

i suspected the firmware was too old for my 4TB disks.
Support for > 3 TB disks was introduced in 4.2.17. What firmware were you running? It seems unlikely to be firmware, since you were able to upgrade the first three disks with no problem.

So seeing as mgdm seems to be retired now, is there anyone who has any idea?
One option is to contact paid support via my.netgear.com.
A second option is to retry the USB recovery using a different flash drive. The NAS can be pretty finicky about what drives it will boot from (and generally older flash drives work out better).
Though maybe first try zeroing one of the older disks in a Windows PC (with either Western Digital's Lifeguard or Seagate's Seatools), and then try booting up the NAS with only that one disk in place. Normally that will do a factory install. If your original extract error was linked to the disks somehow, then it's conceivable that the factory install would work properly.
Here is my suggestion:
Remove all the 4TB drives, labeling them as to order so you can put them back if needed.
Take one of the old 2TB's (or any other spare drive with nothing on it you care about), remove all partitions using a PC (if you can), and install just that drive.
If the NAS then builds a working volume when it's booted, the problem is on your drives. But you now also have a working OS4.2.x system to use to switch to OS6.
Do the switch to OS6, update to the latest OS version, then remove the spare drive, re-insert the 4TBs, and do a factory default. Now, you have a clean up-to-date OS6 system on which to restore your data.
If the system doesn't build a working volume with just the spare drive, then you may have a firmware problem in the flash or some other hardware issue.
- I forgot to add that I already tried doing a factory reset with only 1x 2TB disk inserted, same problem.
Also tried removing all volumes in windows on that disk.
Could try zeroing the disk with a software as suggested..
Not sure which firmware it tries to install with a factory reset tbh, but i suspect that it doesn’t support the 4TB disks.
I will try to locate other usb drives that I can try to get it up and running and upgrading to OS6, but im afraid i might have to resort to paid support, thanks for the link.

Whenever you update/install firmware, the copy in the flash is updated to match.
Aha, then it shouldn't be a firmware problem, it has probably been corrupted by the factory reset then...
