I'd recommend you to try troubleshooting the SATA drive externally via a docking station or a SATA-to-USB cable + adapter. Check if you'd be able to get it recognized like this. In case you are able to detect it, I'd recommend you to use your HDD manufacturer's diagnostic tool to test its health and SMART status. If it's still under warranty, you might also want to contact their customer support and get the HDD replaced. If that's the case and there is important data stored on it, I'd suggest you to get in touch with a professional data recovery company as well.
