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 on front panel to indicate what's going on. I removed both of my disks and the behave is still the same. I've been trying to do OS Reinstall, following instructions in manual. However, even pressing the recessed reset button at the back while power up, the highspeed fan is still running and there is no display at front panel indicating the boot manual. Could someone please advise on how I could overcome this issue?

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. NightOwl2 wrote: Although my NVX is 4-bay, but I only need 2-bay for X-RAID2. 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. NightOwl2 wrote: I was thinking of new options using SSD. 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. NightOwl2 wrote: 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? 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.

It's most likely a hardware issue, not a firmware one. If it is firmware, USB recovery is what you need, not OS re-install. But to be honest, your best bet is to replace the NVX. You can choose another (used) ReadyNAS, or we can help you with ways to recover your data from the drives if you choose to go with another brand of NAS. There is a way to use an OS6 based NAS for data recovery, or you could purchase another legacy ReadyNAS running 4.2.x and just move the drives over. For any kind of data recovery, you'll need a place to put the data. Moving to a replacement ReadyNAS will likely make data recovery unnecessary. But when your NAS died, it could have corrupted the volume in the process and recovery will still be needed. As for what the problem could be, most likely the power supply. But it may be something else. 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.

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? Regards,-- NightOwl2

  The NVX can handle > 2 TB drives. But it cannot be upgraded to OS-6.
