i think all sata port is good, few months ago, all 4 drives some times detected, and suddenly only 3 detected, i though one of them was mallfunction, and now i have a new one, but still can detect 3 drives
I use1 SSD ( for windows system ), and 3 drives HD ( seagate and WDC ), my mobo MSI b150m Pro-VDH ,
I never change the setting from bios because i am new on computer, all default setting
