ReadyNAS RND2000 v1 cannot boot. System Check completes. Starts Quota Check. Then Device not found
ReadyNAS RND2000 v1 cannot boot.
System Check completes. Starts Quota Check. Then Device not found error from RAIDar (Windows)
First I am NOT new to Readynas. Obviously this is an OLD unit which I have had and has been running fine for many years. But suddenly stopped.
So I tried to power down and reboot a few times. No luck.
Found this helpful post about similar problem here:
So I tried this suggestion, to try boot from Disk 2 only.
It is worth trying to boot it up without disk 1, and see if that works (leave disk 2 in slot 2). If it does, then check that your data is there. If it is, then do a firmware update (current firmware is 4.1.16). After that is completed, hot-insert disk 1 (with the NAS running), and it will resync - recreating a redundant RAID array.
But that did not work either.
So I removed Disk 2 and put it back in. Then put disk 1 back in. So back where I started. But I tried to restart anyway and it seemed like it was working...
In RAIDar on Windows it shows both disk drives GREEN.
File system check completes.
Then Quota check & file system check runs and reaches 100%...
Stays there a while and then... Error:
RAIDar could not find any NETGEAR storage on your network. Check that your storage device is powered on and connected correctly. For more help, visit http://my.netgear.com.
HELP please. Anything else I can do or try here to get it running again?

Did you try using the boot menu to skip the volume checks? See pages 15-16 here: http://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf If this works, I suggest updating your backup right away. Don't write more data to the volume until after that is taken care of.
If you need to extract the data, then another option is to try connecting disk 1 to a Windows PC. The PC doesn't support the ext file format, but there is a freeware utility that can access the data - R-linux for windows ( https://www.r-studio.com/free-linux-recovery/ ).
Note the v1 NAS use a somewhat unusual RAID organization - they use a dedicated parity disk, and volume information is in an unpartitioned area of the disk. That still applies to your duo, even though it is using RAID-1 mirroring. So R-linux for windows can't extract data from the C volume on the "parity" disk. That's usually disk 2 - but in some cases it ends up being disk 1. So if you don't see the data on disk 1, it is worth looking on disk 2 (just in case).
First many thanks for your helpful suggestions. I will try those options to skip disk checks etc and see if I can at least access and backup my data.
Also wanted to share a bit more troubleshooting info after many attempts to boot...
On startup
File system check completes
Quota Check
Then System Starting...
Then ErrorSo while it takes a while it does seem to get beyond the disk check stage.
But then the system cannot complete startup.
Does RAIDar give you any clues on what the error is? https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar
