Hello, all! I recently upgraded my older Windows machine to Windows 10 and all is running smoothly so far, with one small detail. My SSD (boot drive with OS) is being seen just fine, but my secondary storage drive is not. BIOS and Device Manager see the secondary drive just fine, but neither File Explorer nor Disk Manager are seeing anything at all. Nothing is showing up to format or anything in Disk Manager. Far as I know, it's plugged in correctly into the mobo and PSU. Any suggestions?
