What does xp use to trigger chkdsk


I am working on a XPe laptop, a Dell D810.  Im trying to figure out what Windows uses to 'trigger' chkdsk on bootup.  is it autochk?

Thank you

Oops, lets try this again!
Windows usually only checkdsks if it shuts down improperly. If the NTFS logfile on the disk says that the drive was/is in use and the computer restarted/bluescreened windows will usually schedule a disk check. The linux NTFS-3G project has a few fun documents on NTFS logfiles if you need a little *non-offical* heavy reading on the subject.

I still think I might be shooting in the dark here, so if this doesn't help can you explain what you are trying to do a little better? Are you trying to figure out what process/service schedules the disk check? are you trying to prevent that?
This site has a quick little tutorial on how to schedule it:

Happy disk-checking!

Thank you, but i was looking more along the lines of how Windows knows to schedule chkdsk  /r on reboot without any user interaction, i.e. a Dirty Disk.  What is the process it uses to monitor the health of the drive?

Ohh, to clarify I'm assuming the disk is using NTFS, not fat32

Yes, the drive is NTFS.  And i do beleive you nailed this question.  i just googled chkntfs, and sure enough, this articale discribes how chkdsk is set to run by the OS.  

In a nutshell, what i am trying to do is explain how this process works to non-computer people, so i needed it in laymens terms.  LOL

Thank you so much!
