ReadyNAS NV+ Kernal Panic
Trying to determine if it's possible to recover from a Kernal Panic situation on the following unit and, if so, get guidance on how to proceed:
ReadyNAS NV+ [X-RAID]
Firmware: RAIDiator 4.1.14 ...

Netgear's service is here: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
Seagate has a service, and they claim support for any NAS. I haven't seen any posts here from people who've used it. But there is information here: https://www.seagate.com/services-software/recover/in-lab-recovery/ Note they don't limit their service to seagate drives.
If you can connect the drives to a Windows PC, then you could use R-Studio or ReclaiMe. Both allow you to see what might be recoverable before you need to pay.

You do a factory reset with the disks installed. See page 23 here: http://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf
Alternatively, zero the disks with vendor tools in a Windows PC (lifeguard or seatools), and just power up the NAS with the disks in place. That will do a factory install. Zeroing the disks is a good diagnostic, it can find drive issues that the non-destructive tests miss.

The incremental data loss since my last backup may not be worth the expense, if it's costly and I can't do it myself, but first I'd like to understand what's involved before I accept the data loss.
Assuming I accept the data loss, what are my next steps to rebuild the NAS with my 3 existing good disks plus the new blank one? [Recognizing that doing this rebuild will wipe the data from the 3 existing disks].
Thanks,

Just wanted to follow-up and close out this thread.
I purchased R-Studio and used it to successfully restore most (but not quite all, unfortunately) of the incremental files since my last good backup in July, from the remaining 3 good drives.
I then reinstalled the 3 good old drives with one new one, and completed a Factory Reset using the procedure given on p23 of the manual, as referenced above.
Everything is back up and running, with a minimal loss of data, albeit after a lot of work. Going forward, I'll be making better use of system alerts to ensure I don't wait too long to replace drives next time, as well as updating my full NAS backup strategy to occur more frequently.
Thanks to both Tony and Stephen for the prompt and helpful guidance.

Hi Dave, apologies I was out of action for a while (family issue), I'm glad you got most of your data back!
Now you *will* keep your backups regularly updated :smileyhappy:!
