# mfsReadDiskID

    Format:	s32 mfsReadDiskID(LEODiskID *diskID)
    Arguments:	disID	LEODiskID structure buffer
    Return value:Error
    Function:	Reads disk ID
    Description:	This function reads the disk ID and stores it in diskID.
    It enables LeoReadDiskID to be handled by using the MFS library.
    When the MFS library is used, using this function may cause a problem in checking whether or not the disk has been exchanged.  Therefore, mfsDiskIdCheck should be used.

    Main errors:
    	MFS_ERR_NO	Normal termination
    	MFS_ERR_DEVICE	Device error
    			An error occurred in an internally called Leo function.
    Since a Leo function error is stored in the variable mfsError, check this variable to perform processing.
