this may provide a handful of additional +clusters of storage at the expense of a significant performance degradation on +RAIDs, flash media or large-sector hard disks. +.IP "\fB \-A\fR" 4 +Use Atari variation of the MS-DOS filesystem. +This is default if \fBmkfs.fat\fR is run on an Atari, then this option turns off +Atari format. +There are some differences when using Atari format: +If not directed otherwise by the user, \fBmkfs.fat\fR will always use 2 sectors +per cluster, since GEMDOS doesn't like other values very much. +It will also obey the maximum number of sectors GEMDOS can handle. +Larger filesystems are managed by raising the logical sector size. +Under Atari format, an Atari-compatible serial number for the filesystem is +generated, and a 12 bit FAT is used only for filesystems that have one of the +usual floppy sizes (720k, 1.2M, 1.44M, 2.88M), a 16 bit FAT otherwise. +This can be overridden with the \fB\-F\fR option. +Some PC-specific boot sector fields aren't written, and a boot message (option +\fB\-m\fR) is ignored. +.IP "\fB\-b\fR \fISECTOR-OF-BACKUP\fR" 4 +Selects the location of the backup boot sector for FAT32. +Default depends on number of reserved sectors, but usually is sector 6. +The backup must be within the range of reserved sectors. +.IP "\fB\-c" 4 +Check the device for bad blocks before creating the filesystem. +.IP "\fB\-C\fR" 4 +Create the file given as \fIDEVICE\fR on the command line, and write the +to-be-created filesystem to it. +This can be used to create the new filesystem in a file instead of on a real +device, and to avoid using \fBdd\fR in advance to create a file of appropriate +size. +With this option, the \fIBLOCK-COUNT\fR must be given, because otherwise the +intended size of the filesystem wouldn't be known. +The file created is a sparse file, which actually only contains the meta-data +areas (boot sector, FATs, and root directory). +The data portions won't be stored on the disk, but the file nevertheless will +have the correct size. +The resulting file can be copied later to a floppy disk or other device, or +mounted through a loop device. +.IP "\fB\-D\fR \fIDRIVE-NUMBER\fR" 4 +Specify the BIOS drive number to be stored in the FAT boot sector. +This value is usually 0x80 for hard disks and 0x00 for floppy devices or +partitions to be used for floppy emulation. +.IP "\fB\-f\fR \fINUMBER-OF-FATS\fR" 4 +Specify the number of file allocation tables in the filesystem. +The default is 2. +.IP "\fB\-F\fR \fIFAT-SIZE\fR" 4 +Specifies the type of file allocation tables used (12, 16 or 32 bit). +If nothing is specified, \fBmkfs.fat\fR will automatically select between 12, 16 +and 32 bit, whatever fits better for the filesystem size. +.IP "\fB\-h\fR \fINUMBER-OF-HIDDEN-SECTORS\fR" 4 +Select the number of hidden sectors in the volume. +Apparently some digital cameras get indigestion if you feed them a CF card +without such hidden sectors, this option allows you to satisfy them. +.IP "\fB\-i\fR \fIVOLUME-ID\fR" 4 +Sets the volume ID of the newly created filesystem; \fIVOLUME-ID\fR is a 32-bit +hexadecimal number (for example, 2e24ec82). +The default is a number which depends on the filesystem creation time. +.IP "\fB\-I\fR" 4 +It is typical for fixed disk devices to be partitioned so, by default, you are +not permitted to create a filesystem across the entire device. +\fBmkfs.fat\fR will complain and tell you that it refuses to work. +This is different when using MO disks. +One doesn't always need partitions on MO disks. +The filesystem can go directly to the whole disk. +Under other OSes this is known as the 'superfloppy' format. +This switch will force \fBmkfs.fat\fR to work properly. +.IP "\fB\-l\fR \fIFILENAME\fR" 4 +Read the bad blocks list from \fIFILENAME\fR. +.IP "\fB\-m\fR \fIMESSAGE-FILE\fR" 4 +Sets the message the user receives on attempts to boot this filesystem without +having properly installed an operating system. +The message file must not exceed 418 bytes once line feeds have been converted +to carriage return-line feed combinations, and tabs have been expanded. +If the filename is a hyphen (-), the text is taken from standard input. +.IP "\fB\-M\fR \fIFAT-MEDIA-TYPE\fR" 4 +Specify the media type to be stored in the FAT boot sector. +This value is usually 0xF8 for hard disks and is 0xF0 or a value from 0xF9 to +0xFF for floppies or partitions to be used for floppy emulation. +.IP "\fB\-n\fR \fIVOLUME-NAME\fR" 4 +Sets the volume name (label) of the filesystem. +The volume name can be up to 11 characters long. +The default is no label. +.IP "\fB\-r\fR \fIROOT-DIR-ENTRIES\fR" 4 +Select the number of entries available in the root directory. +The default is 112 or 224 for floppies and 512 for hard disks. +.IP "\fB\-R\fR \fINUMBER-OF-RESERVED-SECTORS\fR" 4 +Select the number of reserved sectors. +With FAT32 format at least 2 reserved sectors are needed, the default is 32. +Otherwise the default is 1 (only the boot sector). +.IP "\fB\-s\fR \fISECTORS-PER-CLUSTER\fR" 4 +Specify the number of disk sectors per cluster. +Must be a power of 2, i.e. 1, 2, 4, 8, ... 128. +.IP "\fB\-S\fR \fILOGICAL-SECTOR-SIZE\fR" 4 +Specify the number of bytes per logical sector. +Must be a power of 2 and greater than or equal to 512, i.e. 512, 1024, 2048, +4096, 8192, 16384, or 32768. +.IP "\fB\-v\fR" 4 +Verbose execution. +.IP "\fB\-\-invariant\fR" 4 +Use constants for normally randomly generated or time based data such as +volume ID and creation time. +Multiple runs of \fBmkfs.fat\fR on the same device create identical results +with this option. +Its main purpose is testing \fBmkfs.fat\fR. +.IP "\fB\-\-help\fR" 4 +Display option summary and exit. +.\" ---------------------------------------------------------------------------- +.SH BUGS +\fBmkfs.fat\fR can not create boot-able filesystems. +This isn't as easy as you might think at first glance for various reasons and +has been discussed a lot already. +\fBmkfs.fat\fR simply will not support it ;) +.\" ---------------------------------------------------------------------------- +.SH SEE ALSO +\fBfatlabel\fR(8) +.br +\fBfsck.fat\fR(8) +.\" ---------------------------------------------------------------------------- +.SH HOMEPAGE +The home for the \fBdosfstools\fR project is its +.UR https://github.com/dosfstools/dosfstools +GitHub project page +.UE . +.\" ---------------------------------------------------------------------------- +.SH AUTHORS +\fBdosfstools\fR were written by +.MT werner.almesberger@\:lrc.di.epfl.ch +Werner Almesberger +.ME , +.MT Roman.Hodek@\:informatik.\:uni-erlangen.de +Roman Hodek +.ME , +and others. +The current maintainer is +.MT aeb@\:debian.org +Andreas Bombe +.ME . -- cgit v1.2.3
