ReadyNas Ultra 2 RNDU2000 dead after unknown causes
Hello all. Please forgive me if this is in the wrong forum, I didn't find one that said it was for ReadyNAS tech support and difficulties. I have a strange issue with my ReadyNas Ultra 2. It's about 5 years old I would guess, and has really been a pretty reliable product. It has a sticker saying FW 4.2.21, but I kept the automatic updates enabled. Some time last week, the unit stopped responding. It has been doing this from time to time. Last time I found that it took 3-5 reboots before it finally was back online.
In this case however, multiple reboots done seem to do anything to it. When I power the device on, the ACT light goes on, and then out...and then there is no further activity. I can hear the drives spinning up, and there is no change when I remove a drive, or both, swap them, anything. Last thing I tried this morning was the firmware recovery process. In this case, I did use a memory stick with an indicator LED on it, held the reset button for 15 seconds, and it appears that nothing touched the memory stick.
I've done a lot of research and everything has been resolved by pulling a disk, or trying the recovery, but no such luck here. The last two things I have yet to try are a new disk entirely (I dont have any lying around at the moment I dont believe), and a new power supply.
So I have a few questions; first, can I migrate the disks seemlessly to a new Netgear device? I dont have a backup, so if it's dead, it's dead-oh well. It was just my media for plex. Second, if I can't drop it into another NAS, can I safely mount one of the drives to a desktop computer? I wanted to ask before trying...because I am pretty certain the drives are OK. One is older, original to the device, and one is a newer 3TB drive that I swapped in a few months ago. Any guidance is appreciated, thanks.
Thank you for the lead on this. I was able to get all my data off one of the drives. The unit is indeed dead. I received a new power supply from amazon at 12V and 5A, and it just continued the same behavior. I'm pretty confident it's toast. However, with your information on r-linux, I was to gather all my media, and put it on my other NAS devices - so thank you for that.

Start by removing both disks (labeling them by slot), and powering up the ReadyNAS. Install RAIDar on a PC ( https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar ) and see if it can find the NAS. Normally it will find it, and report a diskless status.
If it doesn't, then your either your NAS chassis has failed or your power brick has failed. If it does, the problem is most likely with the disks (though insufficient power can cause a lot of odd symptoms).
Second, if I can't drop it into another NAS, can I safely mount one of the drives to a desktop computer?
You are using XRAID (or RAID-1), correct?
Your NAS uses a linux file system (ext), which Windows doesn't recognize. There is a freeware package you can try, called R-linux for Windows ( https://www.r-studio.com/free-linux-recovery/ ). So start there, and see if it finds your files.
