SOS code on ReadyNAS Duo RND2000 V2
I've been trying to post in this forum but it's been impossible from start to finish. First the country selector on the register page doesn't work. Then I couldn't post a topic because a small empty ...
Did you try booting up the NAS without disk 1 (keeping slot 2 empty). It's possible that the root partition on disk 2 is ok (the NAS normally will try to boot from disk 1).
Do you have a backup of the data on the NAS? If not, you need to off-load (recover) anything you care about before proceding further.

The link posted above says "test the disks with vendor tools." , which tools?
I posted them above -WD's dashboard software for Western Digital, Seagate's Seatools software for Seagate

So 3 slow blinks = "Bad contents on root partition of disks", but it does it even without disks being present.
Are you sure it isn't doing 2 slow blinks without the disks???

The nas says "RND2000 v2" on the back, that's why I put it down as a v2.
The labeling is quite confusing - I think if Netgear had a do-over they would have branded both the Duo v2 and the NV+ v2 differently.

What I would like to ask is, what format does it want the disks to be in for a new installation?
The NAS needs to format the disks, and it will create the root partition and install linux and the NAS application software on it. You can either boot up with formatted disks or you can do a factory default using the boot menu. Pages 15-16 here give you more info on the boot menu options:
In reply to StephenB:
1. "Did you try booting up the NAS without disk 1 (keeping slot 2 empty)" - do you mean with the slot 1 disk only? I can try this.
2. "Do you have a backup of the data on the NAS?" - there is no need to worry about data. I shredded the drives with Killdisk and factory reset the OS. I'm surprised that it didn't understand what to do with fully shredded disks, or ones with a fat32/exfat partition on them.
3. On vendor tools, my drives are Samsung ones. I think "Samsung Magician" might be what I need for that, although it seems primarily aimed at SSDs and not HDDs.ChatGPT also suggested HDDScan so I will try both.
4. If you look at the video from 5 seconds onwards, you can see 3 slow blinks. I'm not sure if it's different with/without drives in.

NO. I meant booting with only disk 2 (keeping it in slot 2).
But that is a waste of time now, since you wiped the disks.

Your video had the disk trays inserted. Unless something is very wrong with your chassis, it will only blink twice without disks.

Not all ReadyNAS have identical behavior in this case, and I don't recall exactly what the boot flash in the original Duo does. But many people wrongly assume that they can just insert PC disks into the NAS with no data loss. So ReadyNAS do have some policies in place to keep that from happening. In any event, the Duo doesn't support exfat.
If KillDisk left the disks unformatted (simpley wiped), then the NAS should have done a factory install when you powered up the system with them in place. That would start after about 10 minutes (to give you time to switch from XRAID to FlexRAID using RAIDar).

I think Magician is specifically designed for SSDs, not mechanical disks. Samsung sold their mechanical hard drive business to Seagate in 2011. So you could try Seatools.
I will come back to this when I have more time to work on it properly and try some things, thanks for your support.
Most of the functions in Seatools will work on any brand of drive.
