[SOLVED] HDD recognized in BIOS but not in device manager nor disk management

I bought a 4TB WD Blue (WD40EZAZ) which I installed with no problems. Showed up in disk management, formatted, partitioned, then I even copied some files over. Then I copied some more files over & it crashed my PC. I waited for a long time hoping for it to resolve itself & ended up doing a hard shut down by holding on my tower's power button.

When I restarted, I checked BIOS & it's still there but when I boot into Windows, it doesn't show up in device manager nor disk management. It only lists my Samsung SSD (boot drive), WD Black (old HDD) & CD-Rom, nothing else. I've tried different SATA ports, different SATA cables & different power cables (I've tried using the cables for my WD Black which I know work). I've checked with WD's Dashboard tool, chkdsk & Crystal disk info & the WD Blue doesn't even show up for any of these.

The twist here is that I thought this was defective, so I RMA'd to Newegg so this is my replacement & I'm still having issues. It's not possible that both drives are defective, right? My gripe is that it all worked without a hitch the first time I installed the first drive.

PC specs (it's old):
Windows 10
i5-750
Gigabyte GA-P55A-UD3
RX570
 

possible motherboard driver is old

I did consider this since my old WD Black is only 1TB. What I'm confused by is that the mobo & Windows did recognize & allow me to partition the 4TB the first time it was installed. I would assume an old mobo that does not support larger capacities wouldn't even allow to do that?
