-#. flag ``ONE_FAT`` - optionally, users can still choose to generate a FATFS volume with a single FAT (file allocation table) instead of two. This makes the free space in the FATFS volume a little bit larger (by ``number of sectors used by FAT * sector size``) but also more prone to corruption.

+#. ``ONE_FAT`` 标志 - 可选参数，支持生成仅包含单个 FAT（文件分配表）的 FATFS 卷。与包含两个 FAT 的 FATFS 卷相比，这样做可以拥有相对较大的可用空间（通过 ``FAT 使用的扇区数 * 扇区大小`` 计算），但会增加 FATFS 卷损坏的风险。
