I have a windows 10 machine I built about 6 months ago. Recently it scans and repairs drive D every time I boot but eventually finishes and windows loads just fine. The thing is I'm not sure that drive D even exists. My OS is on drive C which is a Samsung SSD. When I go to drive D properties it shows the size as 0 bytes. I don't recall ever creating partitions on any of my drives so I have no idea where D came from. I have two other HDDs (E & G) where my files are stored. Should I just delete drive D? If so, how do I do that?
