Can't Get Hdds To Work. Out Of Ideas. Please Help

Please help! My pc recently gave up on me so I basically did a complete rebuild and literally everything is working perfectly except my old HDD wouldn’t show up anywhere, wasn’t in disk management, bios, anywhere. (SSD showed up no problem). I figured it just died with the rest of the old system and got a new one, still nothing. Thought maybe I got a defective unit so I returned it and got another new one, still won’t even spin. I have searched everywhere and feel like I have tried everything. I updated every driver I could think of and messed with everything I could in the bios but still nothing.
Same Power and Sata cables work on SSD but none of the HDDs
I have plugged in just power to see if it would spin up.
Any suggestions would be extremely appreciated
System:
ASRock B365 pro4
Intel i7-9700k
2x Crucial ballistic 8gb DDR4-2666
Cooler master MWE650 gold
GeForce GTX 1060 Oc
Corsair Force 120gb SSD
The old HDDs was a 1tb seagate barracuda and the two new ones are 1TB Western Digital WD10EZEX

 

Spinning has nothing to do with drivers or the BIOS. If you apply power, it should start spinning - even without a data cable connecting.

And what happened?

I realize you said you tried an SSD on the same cables and it worked, but I would still try a different power cable - or even trying the drive in an external enclosure or docking station, or another computer. It is possible you got two new, but faulty hard drives, but that would be some pretty bad, bad luck.

 

this might be redundant, since it appears you know your way around a BIOS, but this is one experience i had getting a hard drive recognized: a new computer came with one hard drive and i added a second hard drive to it. windows refused to see it. the motherboard had a half dozen sata connectors on it. when i went looking through the bios, i was surprised to see that each motherboard sata connector had an off/off switch, and they were all turned off. so i turned them all on, rebooted the computer, but the computer would not boot because the bios was looking for something to be attached to each of the sata connectors. ok, so, i figured out the numbering scheme that the motherboard used for its sata connectors, i turned off the empty connectors, and made sure that the sata connector that the 2nd hard drive used, was turned on. rebooted and everything was fine, the hard drive showed up in windows and was usable. and that's about all i know. good luck with it.

 

@harmless, "each motherboard sata connector had an off/off switch" I will remember that , as I have never come across it - I see the logic of it, though.
I usually check in "Disk Mnagement", or, use Partition Wizard, and if they don't see it, it's usually a good sign of being duff.
