Dead volume on ReadyNAS 204
I have a RN204 that is remote to me and today I had four emails in quick succession:
Error communicating with UPS 'UPS' (Back-UPS ES 550G).

The USB drivers in many UPS aren't well written, so errors on those are fairly common. My own systems log quite a few of them, but the NAS still monitors power correctly. You can test yours easily enough be disconnecting the UPS from the main power, and check that the NAS generates the correct alert.

It happens more often than you might think, but it does seem odd that the NAS reported both of them removed from the unit.
Can you connect the drives to a PC, and test them with vendor tools (Seatools for Seagate, Lifeguard for Western Digital). Label them by slot as you remove them. This should be done with the NAS powered down (and they should be reinserted with the NAS powered down also).

Hi geojay
The NAS had multiple disk failures getting the volume inactive/dead, if this is the case you will need to recover the Data already, You can contact NETGEAR Support for this service, Experts will be able to provide you the cost. (USD200 if I am right for the Data recovery). You will need to get it boot to Tech Support mode if you will have Support check and fix this.
You can send us the logs if you want to, but contacting Support will be the way to go for data recovery.
Regards

Hi,
Thanks for your response. I'm not too worried about the data on the NAS as it's a backup of a PC and is also replicated to another NAS.
Can I ask how were you able to diagnose this failure from the errors I detailed? I didn't find them very informative and also found the UPS error concerning. It also feels like a large coincidence that two drives failed at the same time. I also couldn't find any reference online to the message flashing up on the device's screen. I'd be more comfortable in understanding what happened here if the error messages were more informative and could be referenced online.
Thanks again for your assistance!
