RN104 will not power up
I have two of these RN104 units. I powered both down to tidy up some wiring. One of the units will not power up again. I believe the power down was successful and have no reason to believe the disks have been corrupted, I think just the unit itself or its power supply is the problem. The data is just backups of other NAS drives so I haven't lost anything yet. My second unit has two spare slots. Is it possible to move 2 of disks from the failed unit to the working unit and preserve the data on the disks?
I should add that RAID is not involved... all disks on both units are JBOD.

Failure to power on is definately not due to a volume issue. A a drive drawing far too much current might do it, but that's not a likely scenario given your timeline. When you say it fails to power on, do you mean it does nothing, or do you see a short LED flash or anything? Did you power down via the button or a command in the GUI?
Does it do the same thing with the drives removed? What do you see if you remove the power connection for a minute or two and re-insert it? Have you tried using the power supply from the other unit?
The problem is the external power supply.
For future reference, can anyone answer my question? Is it possible to move JBOD disks from one RN104 to another?
Yes. All the configuration information is on the drives, not in flash. You can move a volume to any other OS6 based ReadyNAS with enough slots, actually, and, if the move was temporary, you can later put back in that NAS's volume and it will be unaffected with one possible exception. That is, that between the OS version on the volume and in flash, the newest will "win". So if one of the NAS has an older version than the other, the end result will be that it will be updated.
Replacement supplies are not hard to find as long as you don't insist on a Netgear labeled one. But not all supplies that use the 4-pin DIN plug wire it the same, so check the pin-out diagram or use one listed for use on a ReadyNAS or a Synology DS410/411/412, which will also work and typically has a slightly higher output amperage rating.
