My hard drives are not detected by windows or disk management.

I assume you have at least one drive that is being recognized - since you can boot Windows?

Since you refuse to state what easy solutions you've already tried, I'll just list the obvious ones:

Have you connected SATA power to the new HDDs?

If you have a modular PSU, check that the SATA power cable for the new HDDs is connected to the correct connector.

Have you tried different SATA connectors on the motherboard? Which ones?

Have you checked SATA settings in BIOS? (Whether any ports are disabled.)

Have you double-checked that all connectors are properly seated? Power connectors should make a small "snap".

My SSD is the only drive that gets recognized yes.

I tried your suggestions and it still does not work

They all have power as i can hear them spinning.

I tried all of my sata connections on the motherboard and checked my settings in bios where everything is fine.

My hard drives are detected by the BIOS (i dont think i mentioned that).

I do not have a modular psu.

The default size of the Disk Management window only has space for 2 disks (in the list in the lower half of the window). If you scroll down, there may be more disks listed.

Disks will not be listed in the list in the upper half before they're initialized.
