-<p>The file system object is the work area needed for each logical drive. It must be given to the logical drive with this function prior to use any other file functions except for <tt>f_fdisk()</tt> function. To unregister a work area, specify a NULL to the <tt class="arg">fs</tt>, and then the work area can be discarded.</p>\r
-<p>If forced mount is not specified, this function always succeeds regardless of the physical drive status due to delayed mount feature. It only clears (de-initializes) the given work area and registers its address to the internal table. No activity of the physical drive in this function. It can also be used to force de-initialized the registered work area of a logical drive. The volume mount processes, initialize the corresponding physical drive, find the FAT volume in it and initialize the work area, is performed in the subsequent file access functions when either or both of following condition is true.</p>\r
