Hello, here is my situation. When booting, with only the ssd plugged in everything goes smoothly and there is no problems once in windows. When booting with both ssd and hdd plugged in, sometimes it will just stay on the loading screen, but one time it scanned and repaired some volume. After booting and loading into windows, the hdd stays at 100% the entire time (hours of idle) with several services being the cause, of which, stopping these services had no effect. In bios the hdd says it is uefi, but I formatted it before I used it. Its only about half full. If I boot then plug in the hdd, explorers progress bar takes forever to load, and usually just stops at about 95%. One time I was given the option to format the drive before using it, but I would like to get some work off it before hand. The drive and system is only 6 months old. Please help, this has been extremely frustrating for the past few months.
