ReadyNAS 102 – Blue light blinking, then no light
Hello, my ReadyNAS 102 stopped working recently, however I don't know when exactly. The behaviour now is that is when I power on the NAS, the blue power light starts blinking, afterwards a constant light, next it seems to reboot, blink again and then no light.
I already used RAIDAR to check if the NAS is found, which often is found while booting, and then it also shows something along the lines of "system is starting up". It also does show 2 drives. When no light is shown, RAIDAR also shows no listing of the NAS.
When the system is still booting, I can ping the NAS and I see it in the file explorer, but obviously I can not connect.
I have read a few threads with similar issues, and wonder if an OS reinstall (https://kb.netgear.com/22892/How-do-I-access-the-boot-menu-on-my-ReadyNAS-102-202-212-or-312) can help in solving my problem. Obviously, I do not want to lose any data on the disk. Are there other means to extract the data, like plugging the drive into another computer and reading the contents there? (I briefly tried, but could not mount the file system type)
Also, before exploring the fora, I pulled out both disks and placed them back into the casing, but I have no idea if the order is correct now. Is there a way to detect this?

Do you know what firmware you are running?
You could try an OS reinstall, though it might not help.
You can't mount the drives on a windows system - you'd need to boot up as linux and make sure btrfs is installed.
What you might try is running the vendor diags on the two disks (seatools for seagate, lifeguard for western digital).
Dear Stephen,
thanks for your reply on this matter.
I checked the following:
- The firmware that is installed on the netgear is 6.6.1
- The SMART status and the regular tests for the disks are ok/pass according to lifeguard
- I attached the disks (one at a time) to a linux machine with btrfs installed:
- The first disk showed the linux partitions and a large empty partition
- The second disk showed a large empty partition (although on osx this shows also the linux partitions)
- "btrfs filesystem show /dev/DEVICE" resulted in "no btrfs filesystem"
- I could not mount the device using the linux mount command
I did not yet try reinstalling the OS, but will do so later this week, if there is no way to view/access the data.
One more question: since the drives are in RAID, do they both have to be attached for me to be able mount them?
Hello smoens,
It is not a good sign that there is just large empty partition on both drives. There is a possibility we are looking at worst case that data is no longer there. Are the drives back on the NAS ? Can the raidar software utility detect the NAS on the network? If it does detect the NAS, there is a way to download the logs from raidar, please download the logs and kindly provide us a copy you through file sharing website like wikisend and just give us the download link.As for the last question "since the drives are in RAID, do they both have to be attached for me to be able mount them?" This will depend what raid level the NAS was set to when it was initially setup.
