My desktop PC which I've used for ~2 years has a 128 GB SSD (Kingston) for OS and drivers and a 1TB HDD (western digital) for pretty much everything else. Both worked fine w/ win 10 for an year, but after I had to change my M/B windows can't seem to find the HDD. My BIOS can find it (so connections should be fine) but it's not visible in windows. Adminstrator or not, Device management, Disk management and resource management (the words may be wrong since my windows is in finnish and these are google translations) don't have the HDD.
