You were absolutely right, it was a RAID 5 setup that I had totally overlooked. Thank you! All better now.

You are totally right, it was RAID 5 setup in the BIOS. Thanks for your help.

Oh duh, that makes sense. I didn’t see any software RAID setup but wasn’t looking for it specifically in the BIOS. Hardware RAID would also make sense. Thank you for the tips!
