Power failure
This morning the device is not working at all - no lights, nothing. The power adaptor is proving 12V, but there is no activity on the NAS.
I'm looking for advice about what to do next. Is there any...
Try removing the disks and powering up - then see if RAIDar detects the NAS. https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar
The NAS chassis isn't repairable. The warranty is 3 years for the original purchaser, so check the warranty status.

If i cant fix the unit then i have very important data on four disks that i want to access. How do i do this?
One lesson here is that RAID isn't enough to protect your data. After this problem is resolved you should put a backup plan in place.
Your options are:
- Purchase a new ReadyNAS and migrate the disks. Any OS-6 model will work for this, though an RN214 would be the closest model to what you have.
- If you have linux skills, you can connect all four disks to a PC running linux (either SATA or via a USB adapter/dock). You can then manually install the data volume.
Thanks for the reply. I have taken the drives out and nothing. No lights, no fan, nada. So RAIDar doesnt get started! It feels like a power supply failure so i'm tempted to buy a new adaptor - must be worth a try @ £13. The pins have 12V on them, but that doesnt mean that it is supplying enough when loaded.
The other thing a thought of was that i should check that the fan works. It wouldn't be the first computer that wont start because of an interlock.
You are right about a backup solution. This has been a long running topic. I used to use tapes but they were unrelaible. These days i want off site storage, e.g. cload storage. The two possibilities that i tried previously didnt seem to work reliably. My latest thought was to sync with another device located somewhere else - but havent got round to it yet.
I don't have a 104, but I am not aware of any ReadyNAS that will fail to start because of a non-fuctioning fan. The power supply does sound like a possibility. Can you measure the input voltage (with the load connected)?
some (long) time ago i had a pc that failed to start because it was monitoring the fans feedback signal to check that they were operating, and one of the fans had died. I wondered if the NAS was doing the same (otherwise what is the point of the feedback signal wire).
I checked the power supply on it's own and i see 12v.
I checked the fan with a separate 12v supply and it works fine, and substituted with another that had monitoring points.
Without the fan connected i see 12v on the pins on the NAS circuit board, but when i plug in (either fan) the voltage drops to nearly zero. So i'm buying a replacement power supply. I'm assuming that there is a high impedance in the power supply - either a damaged cable or dry joint somewhere.
