Method 1: Using CHKNTFS utility
CHKNTFS is a utility that has been developed by Microsoft to disable disk checking on certain drives at Windows startup. To use this utility go to Start –> Run –> cmd.
If you want to disable check disk on C: drive, use the following command on command prompt.
chkntfs /X C:
If you want to disable check disk on two or more drives, just keep on adding the drives:
chkntfs /X C: D: E:
This will disable check disk on C, D and E drives.
If you want to restore what you have done, that is, enable automatic disk checking on all the drives again, just run the following command:
chkntfs /D
This will restore all the drives to automatic disk checkup.
Method 2: Using Registry
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 *
