Cannot recognized newly installed SSD

My laptop failed - screen suddenly froze, mouse did not move, no rainbow wheel of death just completely frozen.

I turned it off and tried to restart but it only made the start up noise. I was able to get use CMD + R to get to the area to reinstall a new OS, see disc utility etc, but computer did not find my hard drive.

i took it to the apple store to see their verdict and they confirmed my SSD was toast. They quoted about $500 to replace with same size but I decided to just try to do it myself and upgrade to at least 500 fb storage.

i installed the new hardrivr - a Samsung NVMe and the adaptor for it, but my Mac still does not recognize the hard drive - can’t see it in disc utility to reformat it so that I can install the Mac OS.

I have gotten the laptop to recognize an external Hardrive which was brand new and I had to reformat with disc utility and load an operating system on there but what am I doing wrong with the internal one?

Is is there something else I can do get it to recognize the new SSD? Could there be something else wrong with the laptop?
