How to stop CHKDSK AT BOOT TIME?

Does anyone know how to stop the CHKDSK command, found under the tools
menu under properties in the windows explorer folder tree, from running
at boot time. It is taking too long to check my external USB drive. I
assume somewhere in the registry I can change a value for all drives
from on to off.

Thanks in advance,
BS

whole thing):

Check Disk runs on every boot.

Open a command prompt...
Start | Run | Type: cmd | Click OK |
Type or paste the following line:


chkntfs /d


Hit the Enter key.


Chkntfs displays or modifies the checking of disk at boot time.


The /d switch restores the machine to the default behavior; all drives are
checked at boot time and chkdsk is run on those that are dirty.


Autochk.exe is a version of Chkdsk that runs only before Windows XP
starts. Autochk runs in the following situations:


Autochk runs if you try to run Chkdsk on the boot volume.
Autochk runs if Chkdsk cannot gain exclusive use of the volume.
Autochk runs if the volume is flagged as dirty.


This can happen if the drive's dirty bit is set.
When a drive's dirty bit is set, autochk automatically
checks the volume for errors the next time the computer is restarted.


This will report whether the dirty bit is set.


Start | Run | Type: cmd | Click OK |
Type or paste the following line:


fsutil dirty query C:


Hit the Enter key.


Volume C: is not dirty
Volume C: is dirty


[[If a volume's dirty bit is set, this indicates that the file system may be
in an inconsistent state. The dirty bit can be set because the volume is
online and has outstanding changes, because changes were made to the volume
and the computer shutdown before the changes were committed to disk, or
because corruption was detected on the volume. If the dirty bit is set when
the computer restarts, chkdsk runs to verify the consistency of the volume.


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.]]

C: is not dirty.

Normally that shouldn't be happening. Chkdsk only runs if the drive is
marked as dirty. Take a look at the troubleshooting tips on Kelly's site:
http://www.kellys-korner-xp.com/xp_abc.htm

Click on "C" and scroll to "Check Disk - Disk Checking Runs Upon Boot"
 
Hi,

Change the following according to your drive letter.

Go to Start => Run and type in "cmd" {without the quotes} to open a
Command window.
Type in "chkntfs C:" {without the quotes}
It should tell you if the dirty bit is set ("C: is dirty"). This means
the drive is flagged to be scanned with chkdsk.
If it is, type in (or copy/paste) "chkntfs /x C:" {without the quotes}
Note the spaces before and after /x
This will prevent chkdsk from scanning drive C: at startup.

To reset it to normal, again open a Command window, and type in
"chkntfs /d"
 
Hi Curt,

Copied it from Google Groups, huh? I can tell by the double spaces. LOL

When I copy my own posts from Google Groups I have to edit them. ;-)
