Welcome to the TH community, protosapien!
I'd suggest you to try resolving this connectivity issue by resetting BIOS. You can use one of the following methods here:

This will get the BIOS settings back to factory defaults, so you'd need to reconfigure them afterwards.
You might also try using a different SATA cable and plugging the SSD to a different SATA port. If you have access to another computer, connect it there as well and see how it will pop up.
If that doesn't help, you should check the motherboard manufacturer's website and make sure you have updated the BIOS firmware to the latest available version. Hopefully, this will get the system to recognize the SSD.
Good luck! Hope I was helpful!
