    If it were my system, I'd test the disks with vendor tools in a windows PC (seatools for seagate, lifeguard for western digital).  Replace any that fail (or which have more than 50 reallocated+pending sectors).

     

    Then do a factory reset with all disks in place.  Reconfigure the NAS and restore the data from the backup.

Thank you for answer.

I have try to make OS Reinstall, device reboot and stuck at "Booting... Checking root FS" (more then 1 hour).

I had a similar experience yesterday with my Pro 4.

Powering down the NAS and using Reinstall OS from the Boot Menu again then worked successfully

    How long you waited for checking root FS?
