Swapping HDDs between different ReadyNas Duo v2
I have a RedayNas Duo v2 that will no longer mount its 2 HDDs. After a power outage and a successful synchronization of the RAID X configuration (started by the NAS itself) and a scheduled power down...

The OS is on both disks, but the system normally boots from the first disk it sees. So I would try booting up with only disk 2 (in slot 2) and see what happens.

Hi Stephen,
thank you for your reply. I have not done any further steps as advised (was out of town) but here is what I found out in the meantime.
The day the system failed, we had construction workers using a shaker/vibrator compacting soil-backfill for the road right next to our house for hours (30 feet from the NAS in the basement).
So, I though I first check if the two disks that were spinning in the NAS at the time took any damage.
I did a SMART check on the disks and have attached the analysis below. Looks like disk 1 is about to fail or has failed already but then disk 2 should have taken over, right? Is the Ready NAS OS only on disk 1? Will it be written to disk 2 if I only insert the original disk 2? Seems that disk 2 is still OK (and the NAS did a full synchronization the day before it failed).
I also found out that the questionable NAS is not questionable at all. I inserted one blank disk (not even from a NAS) into it and it worked fine. I also inserted two disks (X-RAID) taken of another Ready NAS Duo v1 and it worked fine.
I also made sure the the both Ready NAS Duo I have are on same firmware 4.1.16.
Shall I still proceed in the way you recommended?

Hi Stephen, tanks for the advice. I just started with disk 2 in slot 2 (in the NAS where its always been) and the NAS is now back up and running, albeit non- redundant. I will have to find another old 2TB disk to make it redundant again.
Thanks a lot for your help, big relief an my end.
Its time for a new NAS and its too bad that Netgear discontinued the NAS series.
cheers
Andreas
