Lately, whenever I try to run Disk Defragmenter, an error box comes up saying "Disk Defragmenter has detected that Chkdsk is scheduled to run on the volume : (C:). Please run Chkdsk/f." This message comes up whenever I try to analyze. I've tried doing a cleanup first but still get the same results. I also ran chkdsk from the run option in the start menu, but that hasn't helped either. All help will be greatly appreciated and 10 points for the best answer. Thank you.
