ReadyNAS 102 – Blue light blinking, no boot
My ReadyNAS 102 has been working with an issue for a few years. I tried to connect recently and it wouldn't let me. I tried to reboot and it wouldn't so I pulled the power. Now it won't boot up (blue light blinking) so I removed the two drives and tried to reboot just the chassis and again just a blue blinking light. I'm on Mac 10.11.5 and honestly I'm not sure about the firmware version on the Netgear – I haven't manually updated in a while and I can't remeber if it's on auto update! Any ideas on what may be amiss or how to resolve? Thanks.
Edit: I managed to connect to it without drives in via RAIDar – light still flashing but now I know the firmware is 6.5.1.
Hello FreshIdentity,
Booting the NAS with no disks will really not boot up the NAS completely and will give you blinking power light. The OS/firmware, settings and data are stored to the disks.
Perhaps you want to check if RAIDar will detect your NAS with the disks in. By the way, when inserting the disks back to the NAS, please make sure you insert them back to their respective bays.
When RAIDar detects the NAS, it will show the current firmware, the current status and RAID level.
If the RAID level is XRAID (RAID1), try inserting just one disk to the NAS and see if it will boot up and let you access the files. If you get the same problem, try the other disk.

I don't want to be annoying but this isn't a valid troubleshooting step. If the data volume is RAID0 or JBOD, you may damage it.
Hi
Thanks for the response. I used RAIDar and the drive showd up intermittently. I then got a series of e-mail Alert Messages with these errors then it said system shutting down:
Detected high uncorrectable error count: [7136] on disk 1 (Internal) [ST3000DM001-1CH166, Z1F4EDFW]. This condition often indicates an impending failure. Be prepared to replace this disk to maintain data redundancy.
Detected increasing reallocated sector count: [7368] on disk 1 (Internal) [ST3000DM001-1CH166 Z1F4EDFW] 57 times in the past 30 days. This condition often indicates an impending failure. Be prepared to replace this disk to maintain data redundancy.
Detected increasing pending sector: count [7728] on disk 1 (Internal) [ST3000DM001-1CH166, Z1F4EDFW] 51 times in the past 30 days. This condition often indicates an impending failure. Be prepared to replace this disk to maintain data redundancy.
I presume there's an error on Disk 1. Should I remove it and try to reboot off the duplicate disk? (I have two 3TB drives setup with RAID 1)
Now that we know one disk is dead/dying, you can proceed.
If you're 100% sure to have a RAID1 and have one dead disk, then yes, reboot with only the other disk.
If you're in RAID0 or single JBOD and one disk is failed, then your data is gone anyway (though you might be able to clone the disk).
Settings and data are on the disks. There is no point booting without the disks. It will never complete boot without disks.
What you can do is try to boot in Read Only mode via the Boot Menu.
Soooo. I got my new drive today and replaced it as instructed in bay 1. The other drive (Drive 2) then procedeed to sync with Drive 1 (I have a RAID1 setup) and when it finished I got an error saying the drive had synced but volume data was still degraded and now it's resyncing. Now I'm totally confused – have I replaced a drive unecessarily or are both drives bad (but what are the chances of that)?
Patience. This is normal. First, the RAID volume is shaped. Then the data is synced to the RAID partitions on the drives. After the resync has happened and the volume switches from DEGRADED to REDUNDANT after the second run through, everything should appear normal.
Thanks for the advice. So I applied patience. The drive resynced and I got a log saying 'Disk in Channel 1 changed state from RESYNC to ONLINE'. Followed by a message this morning saying 'Volume data is degraded'. It appears to be resyncing again so I'll see what transpires...
