I have recently removed SEVERAL programs from my pc and wish to run disk defrag. When I attempt to run it I get an error message stating" disk defragmenter has detected that chkdsk is scheduled to run on the volume ---C. Please run chkdsk/F."

I have no idea what that message means, I have nothing "scheduled" to run. Rebooting does not help.
Any suggestions?
Very much appreciated!I'm not sure if this will help but have you got any scheduled tasks (de-fragment). Also is atleast 10% of your hard drive free space?I have nothing "scheduled" except for virus scan which has always been scheduled.
15% of my hard drive is free.Will de-fragment begin and then quit PART WAY through? Sorry I'm just trying to get a full picture.Also details of your os and comp would be handy. Cheers mateIt does not run at all (or analyze)....the error message pops up immediately.
