  • What is showing up as an error in your adminstrator system error log?


    How large is your hard drive? defrag cannot work is there is low free space.



    How much memory do you have on board the the system?

    Which version of Xp are you using?

    This is probably your solution Run the chkdsk /f from the adminstrator version of chkdsk /f?



    Are you running the defrg program in the adminstrator account? Applys in Xp


    Tried to install defrag?

    There are several reasons why the built-in defragger may not work properly.

    Here is a procedure I compiled that has been very successful at repairing the XP built-in defragmenter:

    0. There is malware on the system. Solution: Run an Anti-Virus check and also a Spyware check.

    1. The disk is too full (you need at least 15% free space, sometimes 20%). Solution: Delete unneeded files and programs till you have more than 20% free space.

    2. The disk is damaged and needs to be repaired. Solution:  

    a. Open "My Computer" and right click on the drive you want to de-frag.  
    b. Select "Properties" and click on the "Tools" tab.  
    c. Select "Check now" to check the disk for errors.  
    d. Select both options and click "start";

    (It may take a while and the PC may re-start so it can do the check at boot time. Be patient and let it complete).

    3. Disk Defragmenter may be corrupted, needing a System Restore to correct it. Solution:  

    a. Start - All Programs - Accessories - System Tools - System Restore (click to open);
    b. Select a restore point well before you started having problems with Disk Defragmenter;
    c. Start the restore process and let it complete (Name the restore operation something descriptive like "Defrag Repair").

    4. There are other programs running that interrupt the built-in defragmenter. Solution:
    a. Close all running programs.
    b. If you suspect there may be some programs running in the background,
    c. Press Ctrl+Alt+Delete and
    d. Select "Start Task Manager"
    e. Under the "Applications" tab you will find a list of all running applications -- you can close these by selecting "End Task."

    5. If still no luck, try disabling the screen saver when running Disk Defrag (you should pretty much leave the system alone when running the built-in defrag utility).

    6. If still no go, try running the defragmenter in Safe Mode. If it runs, something is interfering with it and tracking the interference down may not be easy. Note: Some versions of Win 7 disable the ability to run the built in defragger in safe mode. If disabled, it will say so when trying to run it in safe mode.

    7. Disk Defragmenter may no longer be on the system or is so corrupted that it needs a re-install. Solution: Re-install the built-in.

    There are several methods to re-install the built-in defragger:

    a. Open the "Start" menu.
    b. Type "%Windir%\Inf" in the "Search" box and press "Enter".
    c. In the window that opens, find the file named "dfrg.inf".
    d. Right-click on "dfrg.inf" and "Install."

    a. Go to "Start > Run" on your computer.
    b. Type "rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 %windir%\inf\dfrg.inf" and press "Enter"
    3. Click "OK" to make the program automatically reinstall itself.

    a. Go to Start >All Programs>Accessories>Right Click on Command Prompt> select "Run As Administrator"
    b. At command prompt, type "regsvr32 dfrgsnap.dll" and hit "Enter."
    c. Type "regsvr32 dfrgui.dll" and hit "Enter." This will reinstall any missing defragger files.

    8. Most problems will resolve by #6 above, but if not and if your windows install is otherwise running fine, you should consider downloading a free trial of a commercial defrag tool as opposed to doing drastic actions to restore the built-in's functionality. Third party programs  are more robust and many work in the background so you can use your PC while defragging.

    Most third party programs offer a free, fully-functional trial (the better ones are for 30 days). Installing one of these will disable the built-in and if you decide to uninstall it, removal will replace the built-in, many times repairing it in the process -- it's worth a try. . ..

    Here is a recent Top 10 Reviews side-by-side comparison of the best defrag programs available:


    a. Select a program and install it. The better defrag programs are automatic and the top placers in the above review can defrag while using the PC. The top placer was the only defrag program that prevented fragmentation (see the review).
    b. Defragment your disk drives.

    Good luck to you!

    PS: If still no go, repair may involve registry editing or repairing the windows installation and possibly re-installing windows itself. These are not simple solutions. If needed, state so and they can be provided.
