    The actual command should be

    chkdsk c: /f

    not chkdsk/f.  When you type that in a CMD prompt, it will tell you it can't run chkdsk on a drive that is being used (or something to that effect) and ask if you want to perform the chkdsk on your next boot.  You reply Yes, and then reboot the computer.

    press the start icon - then left click on "my computer" and right click on "Local Disk (C:) and select properties then select the Tools tab
    then select "chekc Now" on the error checking section - select all boxes and select  start.
    it will complain and say it will schedule one when you next reboot - reboot and DONT touch any thing and wait for the chkdsk to start. - it can take many hours .

    And if you're talking about fsutil and chkdsk, I presume you have placed this in the wrong zone.  It should be Windows XP, and not Windows 98, correct?  (As I am a Page Editor at Experts-Exchange, I can move your question to the proper zone, once you confirm my suspicion...)
