RNDU6000 won't boot - faulty PSU or bricked NAS?

Not sure about L1 tech support, but mdgm almost certainly said you could migrate to another pro or ultra, and that Netgear support could assist you in migrating data to the RN316. That's what he's said several times to other posters. The RN300 (and all OS6 products) are very different from the OS4 firmware running on your ultra. I think you should check the warranty status quickly as you can - if you registered it, then you might be able to get the data from netgear's support site.

StephenB - I just got off the phone with support and they confirm what you said -- the 316 can NOT read drives formatted under Radiator4.2.x or boot from them. They have no idea what either tech support or mdgm were talking about yesterday. However, apparently I can pay $200 for their advanced data recovery service and they'll have a tech remote in and recover the data for me so I can copy it off. This seems to indicate OS6 can read ext volumes, but they won't tell me how to do it.

I feel like I'm missing something obvious here -- I'm thinking there is an ext4 module available or installable, but it's not loaded by default. With a loadable ext4 module I could boot OS6, insert 5/6 of the old drives and then use mdadm to mount the old data (only need 5 of the 6 since its RAID5). And it certainly sounds like I'm not the only person who's had something like a PSU failure on a 4.2.x machine leaving the data nominally intact, but inaccessible..
