Dead RND4000 (ReadyNAS NV+)
Hello, I have an RND4000 (ReadyNAS NV+) that appears to have died. I've replaced the power supply unit and still no action, so I guess it's a circuitry fault somewhere. The unit has a 3-driv...

One more question if you can advise - would the differing versions of RND4000 make any difference in being a host for recovery?
Any NV or NV+ v1 model will work. Note the NV+ v1 needs to say ReadyNAS NV+ on the front panel. Don't worry about RND4000v2 or RND4000v3 labels - they denote small hardware revisions of the same platform. Best to test it with a spare disk first. After installing the spare, either match the firmware to your original NAS or install 4.1.16. Try booting the NAS with the spare disk in every slot.
The NV+ v2 (which says ReadyNAS NV+ v2 on the front panel) will not work. Ultras, Pros, or NVXs will not work either.
Some updates on this. I found a working chassis to inserted a drive (never used in NAS before, not part of the original X-RAID) into slot 4, got it online and did all the firmware updates. So far so good.
I then inserted drive 3 of my 3-drive X-RAID I want to recover into slot 3, and the ReadyNAS has automatically grabbed it and initialized it to use with the other drive I had in slot 4. So basically, of my 3-drive X-RAID with production data I'm now down to 2 with unknown status on them.
My expectation was the ReadyNAS should have read the data on drive 3 of my 3-drive X-RAID, seen it was part of another ReadyNAS RAID and not automatically initialized it. Obviously I'm wrong in this.
Do you have any suggestions on how I can insert the last 2 drives of my 3-drive X-RAID into the new chassis and have ReadyNAS attempt to recover it rather than initialize it?
Thanks,

Unfortunately, yes. The NAS will format any drive that is hot-inserted, and add it to the existing array.

Power down and remove the two drives currently the array. Insert both of the last 2, and power up.
I've done as you advised and the ReadyNAS booted off the remaining 2/3 drives with the original configuration - IP address, credential etc. I can map to my data share and directory list data.
I've opened a few key files to test and that's worked without issue, so I've now inserted drive 3 back into slot 3 and will let it rebuild overnight...
StephenB and Sandshark thanks again, you have my sincere gratitude...
