An update is available that lets the Chkdsk.exe tool compact the NTFS security descriptor stream in Windows Server 2003 Service Pack 2Article ID: 919241 - View products that this article applies to. On This PageINTRODUCTIONIn Windows Server 2003, the NTFS file system does not provide an option to compact the security descriptor stream in the master file table (MFT). Note The security descriptor stream is also known as the $secure file. Therefore, the security descriptor stream may continue to grow and to consume lots of disk space, depending on the file system usage. If the security descriptor stream that is used exceeds a certain threshold, no more security settings can be configured in NTFS. Currently, to compact the security descriptor stream, you must back up the whole volume, format the volume, and then restore the data on the volume. This update adds a new function to the Chkdsk.exe tool so that it can compact the security descriptor stream when you use the /f switch. MORE INFORMATIONAfter you apply this update, the output of the Chkdsk.exe tool may contain information that resembles the following:To determine whether the security descriptor stream has been successfully compacted and to determine how much space has been saved, first run the Chkdsk.exe tool together with the /f switch. Then, run the Chkdsk.exe tool again without the /f switch. Check the KB in use by the system value before and after you use the /f switch. The decrease in the KB in use by the system value after you use the /f switch represents the space that is saved by the compaction. Update informationA supported hotfix is available from Microsoft.
