Hello everyone!

So, here's what happened: I have a secondary PC that doubles as a server. In addition to a SSD that runs Windows, it has four multi-TB HDDs with media files.

I wanted to rebuild this PC with a new motherboard and power supply. I unplugged everything, took the PC apart. Swapped out the motherboard and power supply. Attached just the SSD to the motherboard and did a fresh install of Windows. Then, once Windows was back up and working, attached all four of the storage HDDs to the motherboard.

Unfortunately, two of them are now not showing up. Not in My Computer, not in Disc Manager, not even in the BIOS. I tried new SATA cables, new power cables, new SATA ports -- nothing. Like the two drives just decided to die on me when I took the PC apart.

I suppose it's possible, but I was careful with them when moving them around, and it seems weird that two of them would go.

UPDATE: I tried the HDDs in another PC, and they work perfectly fine. Put them back in the new PC, and nothing. Is there some setting in the BIOS I could be overlooking? Bad motherboard?

Yes.

So like if you think of HDD A,B, C and D -- A and B are working, C and D are not.

I took the exact cables that were attached to working HDD A and plugged into non-working HDD C and no difference.
