So, me and My father just built me a new computer for my 18th birthday coming Thursday, and, as the title states, we used a new drive as the main Windows Drive (a 512 GB M.2 SSD), and we threw the SSD and Hard Drive from my old computer into it as well, to wipe them and then use them as extra storage. (a 128 GB older Samsung Pro SSD, and a 2TB Seagate 7200rpm HDD from before they did the green color re-brand thing).
However, both drives aren't showing up on the new PC, neither in the UEFI or Windows itself, and the strangest thing is that we used the same SATA Cables from the old PC, and the same Power supply (Corsair TX 650), and both were working just fine that same day in my old PC.
And I doubt that it could be the SATA Slots on the Motherboard, as if the SATA Controller was dead/messed up, it likely wouldn't even boot, and even if the slots are dead, the Motherboard likely would notice.
Can anyone help?
For Reference, my old PC was a old Dell XPS Workstation PC with a i7 3770. And my new system is a Ryzen 5 3600, Asrock B450m Pro4. and the M.2 Drive is working fine, and everything else is working fine, GPU (GTX 1070 FTW3), CPU, and RAM, as I am typing this on that new PC;
