mkdosfs(make Dos file system)
mkdosfs(make Dos file system)功能说明：建立MS-DOS文件系统。
语 法：mkdosfs [-cv][-f <FAT数目>][-F <FAT记录的单位>][-i <磁盘序号>][-l <文件名>][-m <信息文件>][-n <标签>][-r <根目录项目数>][-s <磁区数>][设备名称][区块数]
补充说明：mkdosfs可在Linux下，将磁盘格式化为MS-DOS文件系统的格式。
参 数：
-c 检查是否有损坏的区块。
-f<FAT数目> 指定FAT的数目，目前支持1与2两种选项。
-F<FAT记录的单位> 指定FAT记录的单位为12或16位。
-i<磁盘序号> 设置文件系统的磁盘序号。
-l<文件名> 从指定的文件中，读取文件系统中损坏区块的信息。
-m<信息文件> 若以次文件系统开机，而却因操作系统没有正常安装，则会显示选项中所指定的信息文件内容。
-n<标签> 设置文件系统的磁盘标签名称。
-r<根目录项目数> 设置根目录最多能记载项目数。
-s<磁区数> 指定每个丛集所包含的磁区数。
-v 执行时显示详细的信息。
mkdosfs
mkdosfs [options] device [blocks] mkfs.msdos [options] device [blocks]
System administration command. Format device as an MS-DOS filesystem. You may specify the number of blocks on the device or allow mkdosfs to guess.
Options
Create an Atari MS-DOS filesystem.
Specify sector for backup boot sector. The default value depends on the number of reserved sectors, but is usually sector 6.
Scan device for bad blocks before execution.
Create and format a file suitable for use on a floppy disk. The device given on the command line should be a filename, and the number of blocks must also be specified.
Specify number of File Allocation Tables (FATs) to create (either 1 or 2).
Create File Allocation Tables (FATs) of size fat-size. By default this will be between 12 and 16 bits. Set to 32 to create a FAT32 filesystem.
Use the specified 32-bit hexadecimal volume-id instead of calculating a number based on the time of creation.
Force installation to a device without partitions. This is useful when formating magneto-optical disks.
Read list of bad blocks from file.
Set the message to be used when the filesystem is booted without an installed operating system to the contents of the file message-file. The message may be up to 418 bytes in size. If filename is a hyphen, read text from standard input.
Set volume name for filesystem to label. The volume name may be up to 11 characters long.
Set the maximum-entries allowed in the root directory. The default is 112 or 224 for floppies, and 512 for hard disks.
Create the specified number of reserved-sectors. The default depends on the size of the File Allocation Table (FAT). For 32-bit FAT, the default is 32; for all other sizes, the default is 1.
Set the number of disk sectors per cluster. The number must be a power of 2.
Create logical sectors of sector-size bytes. Size must be a power of 2 and at least 512 bytes.
Print verbose information about progress.
