My computer won't run the Windows Disk Defragmenter all the way. It's the first time I've had a problem with it. It gets to about 12%, stops and produces a message that says some files cannot be defragmented. I am running Windows XP Home SP2. The last software I installed was jv16 Power Tools - the paid-for edition - and I used it to clean the Registry.


In Windows 95/98/Me, startup programs were the cause of most such failures, but the Disk Defragmenter (Defrag) in Windows XP isn't usually bothered by startup programs running in the background. I would say that there is either a problem with the hard drive itself, or some open or in-use file is getting in its way, or a security tool is preventing Defrag from moving a system file, perhaps because it recognises it as malware.

To check the C: drive deeply enough, run Chkdsk in Thorough mode, To do that open My Computer, right click on the C: drive, and select Properties => Tools. Click Error checking => Check Now... and place check marks in both check boxes by clicking in them with the mouse pointer. Click Start. A message saying that the disk check cannot be performed in normal Windows mode offers to run Chkdsk during a reboot. Choose Yes, and then reboot the PC to allow Chkdsk to run during the startup process. Because the process takes a long time, the best time to do this is when you are not using the PC for several hours, or run it overnight. When the process is finished successfully, it means that the drive itself is all right. Reboot the PC again, and start pressing the F8 key as the startup begins. Press the key quite a few times in order to catch the moment when Windows is looking for that keystroke. The F8 key interrupts the normal boot process and presents you with a boot menu that includes Safe Mode, which you should select. In Safe Mode, Windows XP runs its most basic configuration that makes troubleshooting possible, because none of the higher functions are loaded. If any antivirus or other security programs are running in Safe Mode, disable them temporarily. To run Defrag from the command line, click Start => Run, and enter defrag c: in the Run box. This activates the most basic version of Disk Defragmenter which has no graphical interface. Defrag should now defragment the whole C: drive. Afterwards, reactivate the security programs, and restart the PC.
