Bad disks detected and blue LED lit
I have a quite old ReadyNAS Duo with two mirrored 1TB disks (Western Digital Caviar Green).
Yesterday after re-booting the NAS I got an error message saying "Bad Disks Detected" with the blue L...
The factory reset seems to have solved my problem with the disks and I can now access the NAS etc. I have also recreated the files. Now what remains is to see if the device will continue to be unstable and in need of os reinstall every now and then.
Thanks for all the help!
Ok, that may be something to look into. After reading about power bricks failing this just might explain why my PC also from time to time has lost the connection with the NAS and hence I have been forced to do a re-boot? If I understand correctly, with power brick you essentially refer to the power supply with it's adapter, right?

Yes.
Thanks! However, it does not seem to be the power supply. With another one it was all the same to start with. Tried OS reinstall again but it would not re boot. After reading more here on the KB I have also realized that I have a v1 and not v2 device...
https://community.netgear.com/t5/New-to-ReadyNAS/ReadyNas-Duo-RND2000-V2-All-leds-flashing-can-t-boot-or-reset/td-p/1040523I continued by analyzing the disks separately using WD Data Lifeguard Diagnostic software and there Disk 2 was ok, but Disk 1 was not even found by the tool, so I guess there acually is a problem with that disk.
So, re-booted with only Disk 2 in tray 2, now the LED for tray 1 flashes in yellow (and is not just grey) indicating that there is a problem with that disk. I had expected grey for "Not present". In RAIDiator FrontView it still says that the system has two disks on volume C: which confuses me.
I am worried putting a new disk in tray 1 could make that one to break to, but that is maybe not likely?
Any ideas? I am also starting to think maybe it would be better just to forget about this device and get a new better one? This one has done nothing but working badly for me.
- Your unit’s a very old one and supports a max of 2TB disks. I would get a new ReadyNAS unit. The RAID format is different so you can’t just move the disks across. Get new disks and copy the data across using backup jobs.

Adding a new disk shouldn't break the disk, but the NAS might not add it properly to the array.

I also have a Duo v1, but it is only used as a secondary backup now. Although it's served me well over several years, it doesn't make sense to invest a lot of time or money on troubleshooting it. A new ReadyNAS is a lot faster, has more features, and doesn't have the 2 TB disk limit. Also, Microsoft is deprecating the SMB 1.0 protocol that the Duo uses. A new NAS would support the current SMB 3.0.
An RN212 (arm based) or an RN422 (x86 based) would both be suitable 2 bay replacements. The RN422 is a bit faster, and has an LCD display (which is often convenient).
Do you think it could be worth a shot at testing a factory reset and re-format the disks? I have all data backed up to a separate external drive aswell, so no risk of loosing data.
