RN31600 Two drive failure within 30 minutes
Hello- I have a RN31600 running 6.10.3. I had a drive go bad about three weeks ago. I purchased a replacement and swapped it out. It rebuilt fine. See the log snip below: Aug 12, 2020 ...
If you have a full backup of your data, replacing the two drives that failed and doing a Factory reset would be an option. Another is what the Community usually suggests, using a recovery software like ReCLAIMe or r-studio and other recommended SWs used by the members here though some of them still have fees to use it's full feature.
If you think your drives are fine by doing a test from a PC and the possibility of the NAS having the problem, it would be best to contact Support for RMA if it's still under warranty.
Also, if your NAS was purchased between June 1, 2014 and May 31, 2016, you have a lifetime chat support available for you to use. If your drives are fine and you just need help on building or mounting back the array this Support option is good.
Otherwise, you will have to pay for a Data Recovery service.

Hi Marc-
I bought it in December of 2017 so I know it's not under warranty. I find it *highly* unlikely that both drives are actually dead. The chance of two drives going out within 30 minutes is pretty far fetched. Most likely it's just the first one that is having an issue.
Is there any way I can contact support prior to paying the $150 to at least see if it's something they can assist with? I'd hate to throw $150 away if they are just going to tell me to use a recovery software/vendor which I'd then have to pay again for.
Thanks.
I logged in via SSH since it's just Linux after all running software raid.

Just to keep people updated....
I tried to manually re-mount the drives through the CLI and nothing showed up. I then reseated them one at a time. Both drives made a clicking/beeping noise. The beeping is the spindle motor trying to start up either because it doesn't have enough power to do so or is running into something, hence the clicking. To rule out power I powered off the NAS and swapped the ports with other good drives.
The clicking/beeping followed the bad drives, so it sounds like both of them decided to go bad within 30 minutes of each other for no reason. Best option at this point is data recovery services....
