    What happens when you try to run CHKDSK? Did you use the right parameters? Go to Start, Run, type in CMD, press enter. Type chkdsk /f (note the spelling, dsk, not disk). It will tell you that the volume is locked and ask you if you want to run it on reboot. Answer y and press enter. Then reboot the PC. Let it run until finished, then it will reboot again on its own. You should then be able to run Defrag.

    If Doc's suggestion doesn't work, use a dos style boot disk and run check disk manually with the "r" switch enabled.
    Allow it to run to completion as it could take a few hours, easily.

    Defrag Won't Run

    Here's a list of successful actions with regards to fixing the Built-in Defragmenter.

    Most situations I have found resolve with these steps:

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

    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 functinality. 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:

    The Gold medal winner is the only defrag program that also prevents fragmentation (see the review).

    Why is it good to prevent fragmentation?

    Basically, it drastically increases your hard drive's life expectancy (especially since you don't have to leave the system on all night -- a much "greener" practice), not to mention it will also increase system performance.

    Check out what the review has to say on this.

    Good luck to you!

    PS: If after all this, 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 this is needed, state so and the procedures can be provided.

    Once you have resolved any of the afore mentioned problems, try Magical Defrag 3 by Ashampoo. I have been using this defrag utility on my desktop and my laptop for three years and have never had a problem. It's inexpensive ($14.99 or less on sale) and it simply runs in the background when your system is idle.
