Chkdsk cannot be run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)"
I'm assuming yes. However I can tell you that every time my computer starts it tries to run it and it always has issues. Not sure the exact nature specifically, but it doesn't like whatever it's seeing. But it always seems to stop scanning after about 18% through part 2, and once in a while it says it successfully defragged but then it always needs to do it again next time.
