[SOLVED] New Hard Drive issues, and old HHD now missing??

[tmcgraw05]

Hey everyone, I'm pretty tech savvy and not really one to ask for assistance, but this has me stumped.
I'm assuming this is either something major or a very silly mistake but I am not sure myself.

So,
I just installed a new SATA Hard Drive (this would be my 3rd drive in all, 1 SSD, and now 2 HHDs) and after installing the new HHD my PC would not boot.
Not even to bios. The RAM inside my case would light up, but nothing further.

So, I assumed the drive was bad. And took the drive out, and removed the wires for the drive.
This left my SSD and old HHD in their same exact spots, however when I booted up my PC, it did in fact boot, but now only my SSD is showing up. (In BIOS and in windows.)

I've tried Windows Disk Manager to see if it was just hidden but this doesn't really make sense to me. Does anyone have some advice?

TL;DR

After installing a new HHD that seems to be defective, my old HHD is not showing up in BIOS or Windows
and cannot find a reason for this or to get drive to show back up.

Any guidance or tips would be greatly appreciated.

I was also just thinking. I also purchased NEW SATA and SATA Power cable, and I'm almost certain this SATA Power cable I bought is defective. Because it does not work with any drives.
And I was thinking this may be part of why these drives aren't working now, but am not sure.

Could a bad SATA Power cable fry a drive or two?
Is this even a possibility? If not, I just wanted to give all the information I could as well.

Start with technical specs of your system, model names of -
motherboard,
hdd, ssd (M.2 or 2.5" form factor),
psu (modular or non-modular).
If modular psu, are you using non-original psu cables?

Show screenshots from Device Manager (drives section) and Windows storage spaces.

Edit: Incompatible sata power cable can damage drive connected.

Specs:
Motherboard: Aorus X470 Ultra Gaming
CPU: Ryzen 7 2700X (W/ Stock Cooler)
GPU: RTX 2060 KO
RAM: Corsair RGB Pro - 3000mhz
PSU: EVGA - 850W ATX (Semi Modular)
SSD: Silicon Power S55 240GB 2.5" (SATA III)
Old HHD: Hitchachi 2TB 3.5"
New HHD: Hitachi Ultrastar 7K3000 3TB 3.5"

So I am currently using the original PSU cables now. But I did attempt to use the NEW and longer SATA Power cable I bought with the HHD right before all this happened.

So I don't know if that could have caused all this, but it seems almost the most likely at the moment.

Can you show link to product page of this sata power cable?
Did you check compatibility with your EVGA PSU?

BTW - EVGA 850W ATX is not a full model name. EVGA has 12x different 850W PSU models

Sorry, I just copied the name from the selling site;

This is a link to the power supply:
https://www.bestbuy.com/site/evga-8...e6re32zv1RhPgVkQzIhoCFPEQAvD_BwE&gclsrc=aw.ds

and this is a link to the Power cable:
https://www.amazon.com/gp/product/B07PXBS54L/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

As you can see the reason I felt comfortable buying this cable, was because the seller has it listed as;

"SATA Hard Drive Power Adapter Cable Only for EVGA Modular Power Supply"

So I assumed this would be just fine..
