Hi, I have a strange problem. So I had windows installed on my m2 ssd, but I had to reassemble my pc ( for an unrelated reason) and somehow the disk vanished. I didn't even touch it, or take it out of the motherboard. I can't find it in bios nor in diskpart tool. I also can't search for it in disk management, because that was my system drive, so I cant access windows. The disk is Patriot scorch M2 PCIe NVMe.
