!–adsense–>Chkdsk (Chkdsk.exe) is a command-line tool that checks volumes for problems. The tool then tries to repair any that it finds. For example, Chkdsk can repair problems related to bad sectors, lost clusters, cross-linked files, and directory errors. For some users this is annoying so if you want to disable follow this procedure.

To disable automatic disk checking at Windows startup through registry, go to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

In the right hand pane, double click BootExecute.

The default value of the key is autocheck autochk *

* means every drive is checked for

consistency. Just add /K:C at the end before *. /K switch will disable autocheck on C: drive at Windows startup. So the final value should look like this:

autocheck autochk /k:C *


If you want to add more drives, the key should look like this: (disabling C and D drives)

autocheck autochk /k:C /k:D *

If you want to restore everything to default, just replace the key with the default one i.e.,

autocheck autochk *

    I needed to use the “PC Regedit” LiveCD in order to modify the registry, because it got stuck at 27% every time and rebooted. Now it’s up and running again.
    Thank you.
