Hello goranfim, Factory resetting the NAS will format the disks, deleting not only the settings but also the data stored to the disks. Always have full backup as we always recommend. Regards,

Hi goranfim,

Welcome to the community!

What is the current status of your ReadyNAS? Could you tell us the recent changes/ made prior getting this error message? Here's a similar thread you can look at.

Looking forward to your response.

Kind regards,

The fix is likely fixing something with your file system. Maybe you've exceeded 85% allocation at some time or something improperly manipulated your disks like a hung device. Can you boot your system in read only mode?

  I had to factory reset the NAS, then it works. All files missing :(
