CAUSE

This problem may occur if you have installed the hotfix that is described in the following Microsoft Knowledge Base article:

329826

(http://support.microsoft.com/kb/329826/ )

Extending NTFS volume fails but appears to be successful

After the Ntfs.sys file is replaced by the 329826 hotfix, a nonpaged pool memory leak in the memory descriptor list (MDL) tag may occur. This leak occurs because the cleanup code that is included in the 329826 hotfix does not clean up the MDL.
