Disk Manager reports incorrect disk usage a while after the operating system starts in Windows Server 2008 or in Windows Vista

View products that this article applies to.

Symptoms

On a computer that is running Windows Server 2008 or Windows Vista, Disk Manager may report incorrect disk usage a while after the operating system starts. The Disk Free Space value is reported to be larger than the total disk space.

For example, assume that you install a 900 GB (gigabyte) hard disk on a computer that is running Windows Server 2008. In this scenario, Disk Manager reports the correct disk usage after you restart the computer. However, Disk Manager reports an incorrect disk usage after a while. The incorrect disk usage may include a Disk Free Space value that is over 1500 GB.

Cause

This issue occurs because the NTFS file system incorrectly adjusts the amount of free disk space in the volume control block (VCB) when the clusters are allocated or deallocated.

Windows Vista and Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.
    VersionProductSR_LevelService branch
    6.0.600
    1.
    22xxx    		Windows Vista and Windows Server 2008SP1LDR
    6.0.600
    2.
    22xxx    		Windows Vista and Windows Server 2008SP2LDR
  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. MUM files and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
