RND4000v2 - RND4000 NV+ v2 - Readynas Wont Switch On Boot Up
Hello All,
I am hoping for some guidance here. I have a Readynas NV+ v2 that wont switch on or boot up.
The power supply has a green light indicator on the inline transformer brick and there are flashing green data inidicator lights on the rear of the machine at the Rj45 port. So there is clearly power getting to the unit and at least some of the circuit board, motherboard is powering on.
This is not the first time I have had this issue. Previously I have been able to strip the unit apart, remove internal cables, rebuild and the unit has been bootable again. The last time this failed to kick it back into action, I replaced the CR2032 (or similar as its from memory) coin cell battery and then was able to boot the machine again.
I recently migrated a lot of the files onto another nas and thought everythiing had been carried over. However, with one of the personal shares for another family member it has come to light that some of their work files are missing. So, I thought all I had to do was boot the machine and carry them over. Except, the unit is not switching on. Again.
I had previously tried to test the power conductors on each of the 4 poles of the power cable. However due to proximity of pins, i did not find that easy when using probes and figured there was more chance I would do damage checking with precariously positioned probes. It has booted up after this. My feeling is that there is a problem with the power on circuit. Eg Front button, or IC that strobes for power on signal.
Given that so many users have had this issue, does anyone know the best resolution. I really dont think its the power supply at fault here.
Lets be clear too, that the main aim is to get the data off that's required from the drives. Configured as Flex Raid. 4 disks and single hard drive redundancy.

It should be possible to mount the RAID array manually in an x86 linux system.
You can also use RAID recovery software in a PC - R-Studio would work. You'd want the $79.99 version.
Note you can see if the software can access your data before purchase.

Thanks StephenB - that works for me, I had concerns that if I tried to put them in a separate linux build there might be a proprietary element preventing me from doing so. Or worse, attempting to retrieve the data could assume a new build and completely flatten the volume / storage pool.
Thanks.
I too have this NAS device - with 4TB of data on it. Configured with RAID 5 and 4 WD Red drives of 2TB each. It has worked fine for years! Recently it just stopped working and disappeared from the list of network devices. I tried the age old trick of turning off and back on again. The device display just reads "Booting...." I left it alone overnight - next morning it still reads "Booting...." The 4 LEDs do not come on. RAIDar only "sees" this device if I power it on no disks inserted.
I have tried everything I have seen on the support pages to no avail including trying to do a factory reset with a non partitioned 2TB hard drive. It is looking like a hardware problem, but I do not have the skills to poke around inside the box in any useful way.
I am keen to access the files on these drives and copy them en mass to a new device. Does anyone have a redundant but working ReadyNAS NV+ v2 chassis they are prepared to sell? Or any other suggestion as to how I can access and copy my files?
Any advice would be much appreciated.

Before you buy a used NAS, you need to be sure of what version your NAS and the one you are buying are. Many users incorrectly believe they have an NV+ V2 (or Duo V2), but really do not, and many are similarly sold mislabeled. I recently looked at eBay and none of the "NV+ V2" or "Duo V2" listings really were V2's.
The problem stems from the fact that Netgear originally used the v2 (and v3) designations on the sticker of the NAS to indicate a minor hardware revision. They later released an entirely different box, incompatible with your volume, and called it a "V2". So, ignore anything on the paper stickers. If it says "V2" on the front of the unit, it's really a V2. An NV+ V2 is also black in color and has an external supply and a V1 is silver with an internal supply. If your NAS (or one you are purchasing) doesn't meet that description of a V2, it's a V1 (which, of course, isn't labeled that way because they didn't know there would ever be a V2).
But your problem really doesn't sound like a hardware one to me. You say RAIDar sees the device when no drives are installed, but not without. Does that include when you installed the spare drive? What does the front display say when you've inserted your volume or just the spare drive?
Can you get into the reset button menu (with at least the one drive installed)? Since you say you did a factory reset with the spare drive, I think you can, and that's a sign the hardware is probably OK.
One thing that can be a hardware one that only affects the unit when a drive is in it is a weak power supply. For most other things, the fact that the NAS is visible in RAIDar without drives is another indication that the hardware is fine. In your case, a corrupt flash may be the issue, which can be fixed using USB recovery.
Have you tried testing the drives in a Windows PC? Generally I suggest using vendor tools (WD's dashboard software for Western Digital; Seatools for Seagate).
Be caretul to remove/insert drives with the NAS powered down. Also I recommend labeling by slot as you remove them, so you can preserve the slot ordering.
Hi Sandshark - thanks to your advice I have made quite a lot of progress towards recovering the data from my failed - ReadyNAS. I think I am tantalisingly close to getting R-Studio to read the data from my 4 drives
I was able to remove the drives, put them into external (USB) chassis and confirm that the drives all appear to spin up as expected.
Using R-Studio and heeding their advice in the manual I decided to avoid changing anything on the 4 drives and get R-Studio to re-create a virtual RAID. I am not 100% certain that I have labelled the drives in the correct sequence so have tried a number of options – I am reasonably sure that the sequence I am now using is correct and R-Studio seems to show that the physical integrity of the disks is good and shows green blocks across all the drives. It seems to be able to find lots of credible file names but I cannot load or read the content and the log file shows this MFT error.
`unexpected MFT record ...` and ending `... check raid for consistence`
The R-Studio support team have suggested I need to check the RAID 5 settings used by the NAS box. Please can you help me to define those settings for the ReadyNas?
It seems R-Studio needs the following - The current values it is using are in bold:
RAID Type: RAID 5
BlockOrderFor: Left Synchronous Standard
Parity Delay: Not used
First Parity:
No of rows: 4
Block size: 64 kb
My research suggests the block size may be the cause of error and that it should be "16 kb".
In parallel with work on the 4 drives I have also been experimented trying to resuscitate the Netgear chassis. Using 2 clean drives I have managed to reinstall the Netgear firmware on the chassis and it seems to be working as it should. I have not tried to reinstate the 4 drives into the chassis to see if it will fully recover the data and functionality – I recognise that there is a risk this will write new content to the drives and potentially corrupt the system further.
I think I am tantalisingly close to recovering the data, but am not sure what safe steps to take next. Any advice you can offer will be very much appreciated.
Unfortunately, I don't know what the correct parameters are. Typically, R-Studio can figure them out.

This is odd, as MFT is the Master File Table for NTFS - and your NAS disks aren't using NTFS. Did you purchase the correct version of R-Studio? (You don't want R-Studio NTFS or R-Studio FAT).
Thanks StephenB - I have checked and I do not have the NTFS or FAT version of R-Studio - as far as I can tell I have the "vanilla" version. The NAS drive had been used to backup the contents of 2 x Windows Server 2008 R2 using a backup utility called Backup Assist - and have over the years successfully backed and restored to/from the NAS. How this was stored on the ReadyNas I don't know.
I have just initiated another R-Studio Auto Scan scan of the NAS disks and am "patiently" waiting for it to complete its work. 😉
