You can manually set the dirty bit by using the ChkNTFS utility or
request that the system set it when using the ChkDsk utility on a drive that is locked. In addition,
the system sets the dirty bit whenever one of a number of errors occurs. Finally, you can modify the
registry so that AutoChk performs specific tasks whenever you boot the system. The Microsoft
Knowledge Base article at
http://support.microsoft.com/kb/q218461/
provides additional
information on this topic.
It??™s important to note the correspondence between commands you enter at the command
prompt using ChkNTFS and the corresponding change to the registry that results in AutoChk running
during the boot process. For example, if you enter
ChkNTFS D: E: /X
at the command prompt,
the system actually enters
Autocheck AutoChk /k:D /k:E *
into the registry. The
/k AutoChk
command line switch excludes the specified drive from checks during the boot process.
Encrypting Data with the Cipher Utility
The Cipher utility provides encryption status information about files and directories on your hard
drive. It relies on the encryption capabilities built into NTFS and doesn??™t work with FAT-formatted
drives.
