Readynas Ultra 4 Plus no valid volume exists #25703630

L3 support rebuilt the volumes so that I could access the volumes on the NAS.  I then bought an external USB drive and backed up all of my data from the NAS.  I have to say that Netgear Tech Support was excellent.  Although the L3 assigned to my case was good, it was impossible to resolve anything with him because he was based in China  +13 hours from me.   Thus, "reboot the NAS" would take 24 hrs or so from whn I woke up and saw the message, to when I found out what I had to do next.  I asked to be assigned an L3 in the USA so that I could at least be near the same time zone, and I received a call from an L3 in California who walked me through all of the remaining issues after we acessed the volumes, to make sur eeverything was running correctly.  All in all, resolution took a while, but $275 was a hell of a lot better than what the local "data recovery" companies wanted to charge ($3000+)!
