its not recommended to cancle the checkdisk at startup.

it runs if it finds the drive as dirty.disabling it may cuase data corruptions.

Still if you want to turn it of open a command prompt and type

chkntfs /?

This is about the same as what subhash chandra has written.
Below is saved information from someones post

Hello, what you're experiencing is what Windows refers to as "setting the dirty bit" and what you have to do is unset that bit. Every time Windows XP starts, autochk.exe is called by the kernel to scan all volumes to check if the volume dirty bit is set. If the dirty bit is set, autochk performs an immediate chkdsk /f on that volume. Chkdsk /f verifies file system integrity and attempts to fix any problems with the volume. It is usually caused by a hard shut down or a power loss during a read-right operation on that particular drive.

How do I fix it, you ask?

Well, that's easy. First click Start> Run> bring up a command prompt by typing in "CMD" and type " fsutil dirty query d: ". This queries the drive, and more than likely it will tell you that it is dirty. Next, type (Copy and Paste) CHKNTFS /X D: The X tells Windows to NOT check that particular drive on the next reboot. At this time, manually reboot your computer, it should not do a Chkdsk and take you directly to Windows

hi Cboy, Exactly.. you are right.

One thing I would like to mention is autochk.exe (A pre mode version of chkdsk) is called by sesssion manager (SMSS.exe) not by windows kernal.
SMSS reads info from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\bootexecute and execute anything mentioned in this multistring value.
The default value is autocheck autochk *

If you disable chkdsk by executing chkntfs /k DriveLetter then the registry will change to autocheck autochk /k:D *
/k tells it to skip check for mentioned volume.
