ReadyNAS NVX (RNDX4210)
My ReadyNAS NVX (RNDX4210) no longer could boot up. After power up, the fan rev up in highspeed mode and staying in this mode forever, without going through normal boot up sequence. There's no display...

IMHO, it's not worth the cost of a replacement supply to repair an NVX (with it not being able to handle drives >2TB nor be upgraded to OS6) and certainly isn't worth a risk buy of one in case that isn't it.
The NVX can handle > 2 TB drives. But it cannot be upgraded to OS-6.
Hi Sandshark,
Thanks very much for your response!
I’m also fairly certain it’s the power supply issue. I couldn’t find any Netgear service manual for replacing PSU, nor details on PSU parts.
I’m purchasing an old RNDX4410 from eBay, arriving later this week. From what I can tell, this is a higher end, close variant of my RNDX4210. If it works as advertised, I’m hoping to move my disks over and be able to access my data for recovery.
Do you think that would work? Do you see any compatibility issue?
I’m also looking for a new solid 2-bay NAS for replacement. The one I have in mind is Asustor Lockerstor 2 Gen2 AS6702T. Do you have any recommendations?
Do you have any advice regarding the data transfer (1.5TB) from my existing readyNAS disks to this new NAS?

The RNDX4410 and RNDX4210 are exactly the same device -- one just shipped with 4 1TB drives and the other with only 2.
Frankly, I believe you made a poor choice unless it was very cheap and you are only using it to recover the data. An Ultra or Pro 4 or 6 bay model would have been a much better choice if you plan to keep using it. They are faster, completely compatible with your current volume (unless already converted to OS6, which you'd have to un-do, but that's quite easy), and convertible to OS6 once you recover your data. Many sellers have no idea of the difference between the 4-bay models, and they are priced similarly even though their capabilities are very different.
When you do get it, you should set it up with a scratch drive and insure the OS version is the same as yours had before you put your NAS drives in it. If you just install one drive, it'll take no time since it has no RAID to create.
FYI, Netgear never provided any service manuals or sold replacement parts. But had you searched eBay, you would have found a replacement supply.
Hi Sandshark,
Thanks for the feedback. So Ultra or Pro 4/6 are later models than NVX and faster? I couldn't find any info on their backwards compatibility, so couldn't decide earlier. Are they also run on OS4, not OS6? Although my NVX is 4-bay, but I only need 2-bay for X-RAID2.
I hesitated to continue running with Netgear since they discontinued NAS and no longer support. Besides, my disks are also old and I don't know when they'll fail too. I was thinking of new options using SSD.
With the new RNDX4410, how critical is it to have the same OS version? Would it corrupt my existing volumes if OS version is different? I don't remember my old OS version and can't seem to find records of it. I'm now very concerned from what you said.

Pro 6 v1: Q4 2008
NVX: 2Q 2009
Ultra: Q4 2010
Pro 4/Pro 6 v2: Q4 2010
As far as performance goes, I think the NVX has about the same performance as the Ultras and first gen Pro 6. All are slower than the later Pro models.
The key limitation is that the NVX has a 32 bit architecture, the Ultra and Pro 4/6 have a 64 bit architecture.
Although not supported by Netgear, the Pro and Ultra systems can be converted to OS-6. NVX systems can't be converted, because OS-6 only runs on 64-bit platforms.

Note the 2 in X-RAID2 has nothing to do with the number of disks. It's just a different implementation of X-RAID than what the older Sparc-based ReadyNAS systems used. They dropped that branding with OS-6, and just went back to calling it X-RAID.
In all ReadyNAS, X-RAID is just a management layer built on top of RAID. With two disks, you are just running RAID-1.

OS-6 has support for SSDs (trim, etc), but OS-4 does not. The hardware is also a problem, as none of the OS-4 ReadyNAS have disk trays designed to accept 2.5" drives. So you'd need to find a suitable 2.5 to 3.5 hard drive adapter.

It depends on the details. If the firmware in the flash of replacement is different than what is on the disks, then the NAS will automatically install the version in the flash. There is no problem when the flash version is newer. But if the flash version is very old, it can be a problem. The best strategy is to do an install using a single spare disk (not in the array), and then upgrade the firmware to the final 4.2.31 version. Then power down, remove the spare disk, and migrate your existing array to replacment. Then power up.
