SYMPTOMS
After you restart a Windows XP-based computer that uses a Serial Advanced Technology Attachment (SATA) hard disk drive, some data on an NTFS file system partition may become corrupted. This problem may occur during shutdown if the computer is using a utility that calls the FSCTL_MOVE_FILE API. For example, the FSCTL_MOVE_FILE API is frequently used by third-party disk defragmenter programs.



CAUSE
This problem occurs because of a timing issue in which a move file operation is incorrectly processed by the NTFS file system when the computer shuts down.
