-<p>The <tt>FATFS</tt> structure (file system object) holds dynamic work area of individual logical drives. It is given by application program and registerd/unregisterd to the FatFs module with <tt>f_mount</tt> function. Initialization is done on first API call after <tt>f_mount</tt> function or media change. Application program must not modify any member in this structure, or any data on the FAT volume can be collapsed.</p>\r
