[SOLVED] M2 not detected

[Xd12c]

I just purchased an HP Pavillion 690-0073W. It came with a tiny 256gb M2 HDD. I decided to add to it and purchased

I figured out that the 2nd M2 slot wasn't compatible, so I bought https://smile.amazon.com/dp/B07F1J7S3F?psc=1&ref=ppx_pop_dt_b_asin_title

I got them both today, plugged the drive into the card and installed it. however, my PC isn't recognizing that it has a new hard drive. Am I missing a driver or setting? The PC is running Windows 10.

TIA

You need to verify the actual protocol of the M.2 port in the HP motherboard.
SATA or PCIe/NVMe.

It's an HP 843B board.

M2 socket, so I think it's a SATA. Which is what I ordered, but it wouldn't fit. It did fit in the PCIe x1 card though

The Crucial P1 is NVMe, not SATA III.
That adapter card you ordered goes in a PCIe slot. And only a "PCIe 3.0 motherboard " slot.

M2 socket, so I think it's a SATA.

But..."M.2" is just the form factor. How it connects.
Might be SATA, might be NVMe. Might be both.

Butt if that Crucial did not physically fit, it is almost certainly a SATA M.2 port.
