In short, you built your PC with a 1TB Samsung 970 Evo M.2 SSD and added a second drive—a Seagate 2TB HDD. You connected it via a SATA cable and used the included data cables. The motherboard is an x570 Gigabyte Aorus Elite Wi-Fi model, and you’ve installed it successfully. It starts up, spins, and vibrates, but it doesn’t show up in your disk management tool.
Certain boards turn off specific SATA connections when M.2 slots are taken. Your setup blocks 5 out of 6 ports if the second slot is used. It’s likely just a matter of connecting your new drive to another port. Whether this happens and which ports are affected depends on the board model and its settings. Check the manual for details.
Reviewed the Owners manual, confirmed Windows boots fine. All tests on the 970 Evo SSD passed so far—no problems detected. Powered off the device, tested all six ports, swapped SATA cables, but the data cable still doesn’t work. Moved to another cable and it finally connected.
It’s unlikely the BIOS is mixing things up, but you could verify your M.2’s listed capacity to confirm any changes. Your setup kept asking about RAID configuration during assembly, which might indicate a misunderstanding.
I concur, verify your BIOS configuration to ensure it isn't set to RAID. For your device, navigate to BIOS > Settings > IO Ports > SATA Config > SATA Mode. Also check if the motherboard detects the drive. This should resolve the issue.
