Hey, recently upgraded PC and had 2 HDD's in previous build that worked fine a week ago and 1 spare that I haven't connected yet. Once i connected them to the motherboard the 2 used ones with files wont get detected in disk management or BIOS at all. Not sure how to find them. Even tried using diskpart and it won't showcase them. Thought it could be some mobo compatibility errors or cable issues. But once I used the one that didn't have any files on it, it seemed to work completely fine and it popped up in disk management instantly. Any idea on how to fix this? (Note: didn't have them connected when I booted and installed windows)
