I own an Asus rog b250f strix motherboard,after installing a ssd in M.2 my HDD stopped showing up,i can't see it in bios or device manager,what happend?
I couldn't find any settings regarding your advice,can you explain again? how those settings should look like? or any keywords i have to keep an eye out for?
If your board is anything like mine, when m.2_1 is populated you lose a SATA port. Refer to your mobo manual and try to plug your hdd in a different SATA port. It should show up then.
