I wasn't sure which information I should attach and I did not want to
spam the list. I was hoping someone would tell me if some of the
relevant information was missing so I could send it when needed.
Could you please tell me what kind of data was missing?

In my case I don't use any HW Raid.
My motherboard is a MSI 870A-G54 -
http://www.msi.com/product/mb/870A-G54.html and I only use SATA and
software RAID.

It's really hard to find the source of the failure.
My first assumption was the drives, since I have 5 more (different) HDs
connected to the board, two in RAID 1 (ATA drives) and they all work
flawlessly.
Reading feedbacks from all the people complaining about the same issue
with the SEAGATE drives as I have I automatically assumed there is a
problems with these particular disks.
