lifesupp on Netgear ReadyNAS NV+ v2
It finally happened - I have the dreaded lifesupp message. I've powered down the unit to hopefully preserve whats there.
3 x 5TB Seagate drives XRAID2 (RAID5), started to get warning messages about increased errors on drive 2 so i began the process of taking a backup. I regularly backup, but over the last few weeks i've begun to digitise a lot of old photos and CD collection. So even the backup is not 100% complete.
I rebooted the NAS yesterday, but the shares were missing (Missing Shares Detected error). They were visible through the dashboard but couldn't connect to them with Mac or PC.
My question is what options do i have? I have a suspicion 2 out of the 3 drives have failed so i'm not holding out much hope.
Would 3rd party RAID recovery software work? Something like R-Studio. Or could Netgear Tech help to confirm if this is something recoverable? It's a very old unit so well outside of any warranty or support period.

Try connecting them to a Windows PC (either sata or usb) and testing them with Seatools (using the long test). Label them by slot as you remove them from the NAS.

- Netgear does offer a data recovery service: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
- R-studio is an option.
- If the disks are reasonably intact, you could try cloning them.
Though you haven't asked, it's best to get NAS-purposed replacement drives (in particular, don't get Seagate DM drives). 5 TB isn't popular now, so you'd need to move up to 6. In this size range, Ironwolf drives are a better choice than the WD EFAX drives.

Disk 1 (Bay 2)
Short test: Pass
Long Test: Fail after 10 minutes (Code F167CCDB)
Disk 2 (Bay 3)
Short test: Pass
Long Test: Pass (10 hours)
Disk 3 (Bay 4)
Short test: Pass
Long Test: Pass (10 hours)
So i'm hopeful that I can still recover the data from the 2 working drives, but why would the NAS suddenly not be able to mount the volumes?
If i try any sort of error correction to recover bad sectors on disk 1, will that risk further data loss?
If i go ahead with R-Studio, should I mount all three disks into a virtual raid, or just the 2 functioning disks?
The errors on NAS boot are as follows:
