After blue recovery screen my nitro 5 AN517-51-530N recovered, but 1 extra SSD memory gone, not visible. I contacted Crucial support, they recommended restart laptop and enter BIOS for 15 minutes, then restart again. It didn't helped. I send SSD memory under warranty and bought new. PCIe 3.0x4 MSI 500GB, but after installation it is also not visible in Storage Management. How this can be fixed. I don't have recovery point to return back. And really don't want to do factory reset as afraid of losing files. I change memory slots, no results. Any suggestions please?
