As a follow-up question... I also have an RN424, a 4-bay version of the same model ReadyNAS on the same network with the same firmware revision the 422 had. Can I remove one pair of RAID drives from the 424 and insert the RAID pair from the 422 and have the 424 read the drives from the 422 so the data could be transferred to a new 4-bay NAS from another vendor?

Almost. What you'd do is power down the 424, remove all the disks (labeling by slot), and then insert the two disks from the RN422. Power up, and you will see all the data - and since the system boots from the disks, the configuration will be identical to the RN422. Same apps, same accounts, same hostname, etc.

You wouldn't be able to leave some of the RN424 in place, you'd need to remove them all before doing the transfer.

When you are done, you can reverse the process (power down again, restore the disks to their previous slots, and power up).

I'm pretty sure the RN422 failure is the internal power supply. The external power supply works fine, still delivering 12 volts. But the 422 is completely dead electrically. No response to the front panel buttons, no activity LED on the Ethernet ports, no cooling fan spinning, and no activity from hard disks. How do I get a replacement power supply? Is there a thread here that discusses replacing the internal PSU? I've got the tools and skills to do a power supply replacement.

A better question for Sandshark

But I don't think it is possible to repair or replace the power circuitry inside the chassis.
