Ok great, that seemed to have worked just fine!
I'll do a parity check tonight regardless and check all files.
My guess is that my old drives started to shout out SMART-errors due to spin-up and down all the time or head parking due to the fact that they were drives from USB-harddrives that i salvaged. 2,5 inch, 4tb each. And I think there was some energysaving hardcoded into their pcb. That the bios couldnt override.
But now I've updated to Ironwolf instead. So, do you think there's some setting I should check to make sure to lengthen the life of my new drives?
CPU temp is 29 C, motherboard is 30C and drives is 25C
