RN104 Cannot Detect Disks
Did my best to search for related problems but found nothing that helped. My month old RN104 won't start. The display shows Booting..., then stops with Err: Cannot Detect Disks. The web interfa...
So you get that status no disks detected when you try to boot even when using a known working spare disk (must not be from your array)? The NAS can boot with just the one disk. A factory reset will wipe all data, settings, everything off the disks installed in the NAS at the time, but even if you don't do that you should still get a different error if it detects the spare disk and fails to boot.
Contact support. Sounds like an RMA is needed.

I had 'ERR Cannot Detect Disks' message too and have done the above maneuvers. Consistently when I have tried to reboot the LCD screen says 'booting...' and I hear an audible wind up sound and then a 'click' and this repeats over and over and then the 'Err Cannot Detect Disks' message appears on LCD screen. I'm certain that I have a disk issue and the 'click' is additional evidence of this (I can boot up with a spare disk and get 'used disk' msg and have 'format' option on RAIDAR front screen). My question is this, if I now want to replace a disk, where do I start? I didn't ever see any warning that any of the disks were approaching failure. I think this was sudden disk failure without forewarning best I can tell. Thanks in advance for any insight/help.
If you have access to a Windows PC, then the best thing to do is check the disks with the vendor diags (seatools for seagate, lifeguard for western digital).
Another option is to power down the NAS, and remove drive 1. The boot up, and see what happens.
If it fails, power down again, reinsert disk 1 and remove drive 2.
Repeat until it boots, or until you've tried with each disk removed.
FWIW, disks fail w/o warning about 35% of the time. (that's per a google study conducted some years back).
