No it doesn't - I have to pull the plug from time to time, and haven't lost data. However, many stories on data loss begin with an unexpected power cut, so I always recommend a UPS for your NAS.

It is possible that your data is still there, but that there is a problem mounting the volume (potentially fixable). However support would probably need to charge - so perhaps just restoring from back is the easiest path forward.

Well I tested it a few times after clean factory resets and the device lost it's volumes every time it lost power.

And I'm quite sure it wasn't doing anything when I pulled the power cable

This sucks because now it's impossible to trust this thing.

All I can say is that I have pulled the power quite a few times on both my RN102 and my RN202 and didn't lose data.

However users here have sometimes lost data after unexpected power cuts, and I once lost data on an old duo v1 that way - so I always recommend UPS protection.

  After you run into the problem can you send me your logs (see the Sending Logs link in my sig)?
  
  Also there is newer firmware now available (6.5.0).

    I have this issue every now and then, albeit with a legacy readynas pro running os6: No disk is recognized when the nas is switched on, and I have a UPS. In my case I solve the issue by switching of the NAS and unplugging the powercord for a minute or two. In my case it is the unplugging of the powercord that makes the difference (static charge anyone?). I now it is a long shot but maybe this is the case for you too.
