.Dd September 16, 1993 .Os .Dt FDFORMAT 1 .Sh NAME .Nm fdformat .Nd format floppy disks .Sh SYNOPSIS .Nm .Op Fl q .Op Fl y .Op Fl v | Fl n .Op Fl f Ar capacity .Op Fl c Ar cyls .Op Fl s Ar secs .Op Fl h Ar heads .Nm .Op Fl r Ar rate .Op Fl g Ar gap3len .Op Fl i Ar intleave .Op Fl S Ar secshft .Op Fl F Ar fillbyte .Op Fl t Ar steps_per_track .Ar device_name .Sh DESCRIPTION .Nm Fdformat formats a floppy disk at device .Ar device_name . .Ar Device_name may be given either with a full path name of a device node for a floppy disk drive
q e.g. Pa /dev/fd0 , or a default name in an abbreviated form
q e.g. Em fd0 . In the latter case, the name is constructed by prepending
a /dev/ and appending a .Em .capacity to the .Ar device_name . Note that any geometry constraints of the device node
q minor device number are meaningless, since they're overridden by .Nm .
p The options are as follows: l -tag -width 10n -offset indent t Fl q Suppress any normal output from the command, and don't ask the user for a confirmation whether to format the floppy disk at .Ar device_name . t Fl y Suppress confirmation request by automagically responding "yes", but still report format status. t Fl f Ar capacity The normal way to specify the desired formatting parameters. .Ar Capacity is the number of kilobytes to format. Valid choices are 360, 720, 800, 820, 1200, 1440, 1480 or 1720. t Fl n Don't verify floppy after formatting. t Fl v Don't format, verify only. t Fl c Ar cyls Number of cylinders: 40 or 80. t Fl s Ar secs Number of sectors per track: 9, 10, 15 or 18. t Fl h Ar heads Number of floppy heads: 1 or 2. t Fl r Ar rate Data rate: 250, 300 or 500 kbps. t Fl g Ar gap3len Gap length. t Fl i Ar intleave Interleave factor. t Fl S Ar secshft Sector size: 0=128, 1=256, 2=512 bytes. t Fl F Ar fillbyte Fill byte. t Fl t Ar steps_per_track Number of steps per track. An alternate method to specify the geometry data to write to the floppy disk. .El If the .Fl q flag has not been specified, the user is asked for a confirmation of the intended formatting process. In order to continue, an answer of .Dq y must be given.
p Note that .Nm does only perform low-level formatting. In case you wish to create a file system on the medium, see the commands .Xr newfs 8 for an .Em ufs file system, or .Xr newfs_msdos 8 for an .Em MS-DOS (FAT) file system. .Sh DIAGNOSTICS Unless .Fl q has been specified, a single letter is printed to standard output to inform the user about the progress of work. First, an .Sq Em F is printed when the track(s) is being formatted, then a .Sq Em V while it's being verified, and if an error has been detected, it will finally change to .Sq Em E .
p An exit status of 0 is returned upon successful operation. Exit status 1 is returned on any errors during floppy formatting, and an exit status of 2 reflects invalid arguments given to the program (along with an appropriate information written to diagnostic output). .Sh SEE ALSO .Xr fdc 4 , .Xr newfs 8 , .Xr newfs_msdos 8 .Sh HISTORY .Nm Fdformat has been developed for 386BSD 0.1 and upgraded to the new .Xr fdc 4 floppy disk driver. It later became part of the .Fx 1.1 system. .Sh AUTHORS The program has been contributed by .An J\(:org Wunsch , Dresden, with changes by .An Serge Vakulenko and .An Andrey A. Chernov , Moscow.
