I just transferred my PC setup to a new case that previously housed another computer, and now I'm facing an issue where none of the three hard disk drives (HDDs) are being detected via the SATA connections. The motherboard recognizes my Samsung 850 Pro SSD in all four SATA slots when I test them but doesn't detect the HDDs at all. The power cables seem to be functioning since they're powering the case fans as well. Here's what I've tried so far to troubleshoot the issue:
1. Switched out the SATA cables.
2. Checked and reseated all power connections to the HDDs and the power supply.
3. Plugged the SATA power cable into a different port on the PSU.
4. Verified that the HDDs work externally.
The odd thing is that all these drives worked perfectly in the previous case, which had a smaller power supply unit (PSU). Does anyone have suggestions for what I should check next?

What models are the HDDs? Are they standard desktop drives, or are they enterprise drives that were repurposed? Certain models, especially enterprise ones, can have compatibility issues with consumer motherboards.
Have you checked if the HDDs are visible in the UEFI or BIOS? This could help confirm if the issue is hardware-related or software-related. If they aren’t showing up there either, that could point to a connection issue or a failing drive.
Nope, none of the drives are showing in UEFI/BIOS or in Disk Management once I log into Windows. I can see the SSD and Blu-Ray drive being detected, but not the HDDs.
The HDDs are two WD100EMAZ models and one WD200EDGZ. They were all taken from external enclosures and worked fine before I swapped the PSU.
