Hard drive not recognized?

Hello friends, I've just built my first PC and installed three internal hard drives (1x SSD, 1x HDD, 1x HDD).

The SSD was recognized normally, and I can use it. One HDD is displayed in the BIOS, but it's not visible in Disk Management. The third HDD isn't even recognized in the BIOS. Now I don't know what to do…

I connected all hard drives normally with new cables in the SATA ports and also in the power supply.

The two HDDs are a few years old, but that shouldn't make a difference.

If it helps, these are the components I installed:

Graphics: MSI 4090, CPU: intel i9 13900ks, RAM: Corsair Dominator 64 GB DDR5, motherboard: Asus Rog Maximus Hero z790

I ask for help.

What you see in the UEFI are NOT the disks – they are the SATA ports.
Using the screenshots, you cannot see whether or not the problematic disks are detected by the UEFI.

The two HDDs are a few years old, but that should not make any difference.

It doesn’t just make a difference – it’s completely irrelevant.
