How to Disable Chkdsk

Chkdsk is a command-line tool that evaluates disk drives and volumes for problems. Chkdsk then attempts to repair and fix any problem that has been detected. Problems that are checked for and fixed include directory errors, lost clusters and bad sectors. The tool runs at startup if the computer is improperly shut down or the hard disk appears corrupted. The chkdsk utility can take up to several hours to check the volume and hard disk. In this case, it may be best to disable the chkdsk tool at startup and schedule a manual check at a later time.

Instructions

1. Click "Start" in the system tray and then click "Run." Type "regedit" in the Open box and press "Enter" (Windows XP).
   Click "Start" in the system tray and type "regedit" in the Start Search text box and press "Enter" (Windows Vista).

2. Navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager" in the registry.

3. Double-click on the "BootExecute" key in the right pane of the window.

4. Add "/k:C" to the end and just before the "*" in "autocheck autochk*" value. The value should read "autocheck autochk /k:C *" when entered.

5. Reboot your computer. The chkdsk function is now disabled.

Tips & Warnings

• Do not make any changes in the registry if you are not comfortable or familiar with the settings. Making the wrong changes can permanently damage your computer and make it inoperable.
