So guys I have ran the third check(except few bios settings & removing 2 drives off a controller, nothing changed).
All errors have dissapeared. I repeat!
This is great news, but I am still not sure how and why is this happening. Bcs im not sure what is happening with my unraid server.
I will try the upgrading parity drive and on Thursday i am installing a new controller card JMB585 and hooking up all the disk to it (read that since 6.1 onwards i can switch up ports).
Thank you for your help.
