SYMPTOMS
After you restart a Microsoft Windows 2000-based computer that has RAW Dynamic disk mirrored volumes or RAW RAID-5 volumes, your volumes may resynchronize. Although the Disk Management snap-in typically shows the Resynching status of RAW Dynamic disk mirrored volumes or of RAW RAID-5 volumes only after an unexpected restart operation or a system crash, the resynchronizing operation may occur after every shutdown. This resynchronizing operation occurs if a write operation was performed on the RAW Dynamic disk mirrored volumes or on the RAW RAID-5 volumes before the shutdown. This symptom does not occur on volumes that contain a formatted file system such as the following file systems:
 * FAT
 * FAT32
 * NTFS file system

Note A RAW volume is a volume that was never formatted and does not contain a file system such as FAT, FAT32, or NTFS. A RAW volume is typically written to by a program that does not require a file system. The program performs direct I/O to the RAW volume instead. For example, Microsoft SQL Server does not require a file system. It performs direct I/O to the RAW volume instead.



CAUSE
This problem may occur if one or more RAW volumes were not registered for shutdown notification. Therefore, the volume or volumes appear to have been shutdown &quot;dirty.&quot;
