Dismounting a volume is useful when a volume needs to disappear for a while. For
example, an application that changes a volume file system from the FAT file system
to the NTFS file system might use the following procedure.
To change a volume file system
Open a volume.
Lock the volume.
Format the volume.
Dismount the volume.
Unlock the volume.
Close the volume handle.
A dismounting operation removes the volume from the FAT file system awareness.
When the operating system mounts the volume, it appears as an NTFS file system volume.
