RN51600 – ReadyNAS 516 6-Bay, Diskless won't boot any longer
Hello folks - Came to my PC to discover that the NAS 516 wasn't accessible and had an error code of "MOUNT_BLOCK_ROOT+25" - I searched the forum and saw this issue already. I created a USB recovery...

Although it is out of warranty, you can still get paid support.
Also, if you purchased between 1 June 2014 and 31 May 2016 you have lifetime chat support at my.netgear.com. So take advantage of that if you have it.

Hi Stephen,
I did purchase between those dates and checked warranty for the device - it's covered for chat - is that done via this channel or somewhere else?
thanks

would anyone know if I purchased an RN3138 could I retrieve the data from the existing HD that I mentioned earlier?
thanks!

You'd use my.netgear.com for that.

It is possible to migrate disks from an RN516 to an RN3138. Whether your volume would mount or not if you did that is another matter.
I am a bit puzzled by the "RAID [2] WD RED 6.0 TB [SATA / 64MB Cache WD60EFRX]" bit in your original post. Can you provide more information on the the disks in the NAS (number and model), and the number and type of RAID volumes you've set up?

Sorry for the confusion, I have a lot of information on those drives and really need to retrieve it - regretting not backing up to the cloud.
I have 2 drives installed in the ReadyNAS 516 and the system setup the RAID, I don't know much more than that
the drives are labeled
6.0 TB
SATA / 64MB Cache
WD60EFRX
NASware 3.0

I submitted a reqest for support on the my.netgear.com but haven't heard back yet and assuming it's due to day/time - yesterday being Sunday in the US.
Appreciate an insight to either get the NAS functional or the information off of the drive/s

Then the system should be running RAID-1. The two disks are mirrored. One possibility is that some cached writes got lost when the system crashed - then the volume could be out of sync and wouldn't mount. It's also possible that the disks have failed - you could try downloading the full log zip file, and look for errors in system.log and kernel.log.
If you want to use paid Netgear support (or the free live chat), then you should do that first - and not attempt to fix anything while you are waiting. Trying to fix it on your own runs the risk of making the data harder (or even impossible) to recover.
If you want to proceed on your own, you could try
- powering down the NAS
- removing disk 2
- booting up in read-only mode using the boot menu
If that works, you should immediately back up all the files on the NAS. If it fails, you could try it again with only disk 1 in place. Make sure you power down the NAS before adding/removing the disks.
If those experiments fail, then you could try connecting the disk to a Windows PC, and trying ReclaiMe data recovery software. It is free to try, but you would need to pay to recover any files.
