Dead RN104, is data recovery possible?

Hello everyone, Recently my RN104, running firmware 6.10.8, died. I've been looking around and have come across a couple different ways to potentially recover the data and was hoping to get a li...

A storm caused a surge through the phone line. It took out my modem, the access point that was connected to the modem, and the NAS which was connected to the access point. I felt like an idiot, and still do, for not having some type of surge protection on the phone line.

All the power adapters for the previously mentioned devices were connected to a surge protector, and seem to be working fine. The NAS power supply lights green, and I don't notice any flickering when attempting to start the NAS.

It happened overnight, so I'm hoping the NAS was in standby mode and there isn't any cached data.

I have a little experience with Linux, so I'm not afraid to give that a shot if it comes down to it.

Thanks for the reply and info about the other models. It's definitely something I will keep in mind.

Does RAIDar find the NAS when it's on the network?

If it does, what status is it giving you?

If not, try powering down, removing the disks, and powering up again. See if the NAS reports a diskless status in RAIDar.

It doesn't power on either with or without the drives installed.

  I suggest doing a risk-buy of replacement power adapter. For instance,

  If you can connect the disks to a PC (SATA or USB adapter/dock), you should also try testing them with vendor diags:
  
  seatools for seagate
  
  dashboard for western digital

    The power supply does sound like a probable cause of your issue since it won't power on at all. It is unlikely a power surge would make it though the external power supply and harm the NAS, at least without also doing damage to the supply. That the LED on the supply lights without any flicker isn't that good an indication it's OK.
    
    Now, I'm only talking about a surge that came in on the power line. If you had a very local lightning strike, it could have come in via the local ground, and that's different.
    
    If it turns out not to be the supply, then you'll have one if you go to buy a used ReadyNAS, some of which don't come with the supply.
    
    Note to everyone: At my home, the cable company (aka network provider) sunk a separate ground several feet from the power ground. That's a bad thing for a local lightning strike, as those two grounds could momentarily be at different potentials and current would flow through the path of least resistance, which could be your TV, cable modem, or whatever. I ran a 0 gauge wire between the two to be the new path of least resistance. Don't count on any surge protector for a local lightning strike. That bolt just traveled 5 miles or more through air -- a little surge protector isn't going to stop it now. But some surge protectors do have a warranty that replaces attached devices, so maybe there is some value in this case. Of course, I do live near the lightning capital of the US.
