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.
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.
