RND4210 connection problems
Help needed - and much appreciated My Readynas+ RND 4210 (v3) boots fine, but does not show up on any of my machines. The display panel shows a "no network link" error message. The cable is che...
In case you do your own research here, what you have is referred to here as an NV+ V1. Yes, I know yours has a sticker that says "V3", but Netgear re-used the version number to create an entirely different ReadyNAS NV+ V2 and really made things confusing. I expect it was a marketing decision to ride on the coattails of the popular NV+, even though the new NAS was a complete overhaul of the hardware and firmware.
But on to your problem. You mentioned you have RAIDar, and I'm going to assume the NAS doesn't show up there, either, or you would have mentioned it. But it can help if you watch and see if it shows up while booting and then disappears. A firmware corruption is a possibility, especially if it's on RAIDar during boot and not later, so OS recovery may help.
Also, try removing the drives (marking them so they go back in the original order) and booting without them and see what the display and RAIDar say.
But, it does sound more like like a problem with your Ethernet port. Do you see any activity on the LEDs at the port? Is the router/switch it's plugged into a "green" one (they are usually advertised as such)? That kind of switch auto-adjusts the voltage level of the Ethernet signals and a failing transceiver on a NAS can sometimes still communicate with a non-green device and not a green one, at least long enough to get your data off. If you have another one you can plug into, try that. A direct connection to your PC is another option if you don't have another router/switch to connect to, but you have to set the IP address of the PC to one in the 168.168.168.xxx sub-net to which the NAS defaults.
There is no way to access the NAS other than via Ethernet. Netgear does offer a service to assist you in data recovery using a current model NAS and there are ways to access the data via your PC and some special software or a native Linux system if you have a way to connect the drives. You cannot simply move the drives into a current model ReadyNAS, however.
A used NV+ V1 is yet another option, but you would be buying a very old device whose history you do not know, so you have to use some caution there.
Sandshark!
Many thanks for the quick reply and your pointing towards it being a NV+ V1.
There is a sticker that says RND4210 and v3 is printed behind it on the actual case.
After reading your comment, and given that my NAS has 4 drives, I started doubting the entire 4210 marking.
And, in very small print, I actually found a marking that suggests it is a RND4450, which in turn shows up as a NV+ v1 on the Netgear support site. Case confirmed.
(I detailed the above in case others have the same problem)
Thanks!
When booting without the disks, I get the error message "BIOS INFO: Eth Link Fail..." on the NAS panel. Guess that is pretty conclusive as well.
Assuming the ethernet port cannot be replaced, I am looking at a data recovery job.
There are a few used NV+ drives on eBay, but prices are high (and will get silly once I add shipping, VAT and customs duties for Norway), and I share your concern over the history of old devices.
Keeping my fingers crossed that Netgear has a data recovery service in Norway.

The diskless model is RND4000. Anything after the RND4 relates to the number and size of the disks Netgear provided. The RND4210 means that Netgear sold the NAS with two 1 TB drives. The RND4450 means that Netgear sold the NAS with four 500GB drives.
But of course folks will replace disks and expand storage over time.

There are other data recovery services that can offload data - especially since it is likely that there is no file system corruption. If you can connect at least three of the disks to a you can mount the data volume yourself. With Windows or a Mac, you'd purchase data recovery software - for instance, R-Studio ( https://www.r-studio.com/data-recovery-software/). With Linux you can mount the array without any purchased software.
Thanks Stephen!
I can't believe my luck. Yesterday I found a brand new, unopened RND4000 cabinet on a local classified site.
Expensive, but much cheaper than data recovery and less effort than a Linux setup.

Great.
Make sure it is an NV+ (v1) and not an NV+ v2. They are very different platforms. A simple way to tell is to look at the front panel. The NV+ will say ReadyNAS NV+, the NV+ v2 will say ReadyNAS NV+ v2. Other labels are confusing, so just ignore those.
Assuming it is a v1, then you should check the replacement out first, and update the firmware to 4.1.16. Use a spare disk (not in the array). Do a factory install with just that disk in place. Then update the firmware (assuming it won't be running 4.1.16). After that, power up the system with the disk in each slot, and make sure it boots successfully.
Then power down, and migrate the disks - preserving the slot order.
