-.SH NAME
-fd \- floppy disk device
-.SH CONFIGURATION
-Floppy drives are block devices with major number 2.
-Typically they
-are owned by
-root:floppy
-(i.e., user root, group floppy) and have
-either mode 0660 (access checking via group membership) or mode 0666
-(everybody has access).
-The minor
-numbers encode the device type, drive number, and controller number.
-For each device type (that is, combination of density and track count)
-there is a base minor number.
-To this base number, add the drive's
-number on its controller and 128 if the drive is on the secondary
-controller.
-In the following device tables, \fIn\fP represents the
-drive number.
-.P
-\fBWarning: if you use formats with more tracks
-than supported by your drive, you may cause it mechanical damage.\fP
-Trying once if more tracks than the usual 40/80 are supported should not
-damage it, but no warranty is given for that.
-If you are not sure, don't create device
-entries for those formats, so as to prevent their usage.

-.SH DESCRIPTION
-\fBfd\fP special files access the floppy disk drives in raw mode.
-The following
-.BR ioctl (2)
-calls are supported by \fBfd\fP devices:
-.TP
-.B FDCLRPRM
-clears the media information of a drive (geometry of disk in drive).
-.TP
-.B FDSETPRM
-sets the media information of a drive.
-The media information will be
-lost when the media is changed.
-.TP
-.B FDDEFPRM
-sets the media information of a drive (geometry of disk in drive).
-The media information will not be lost when the media is changed.
-This will disable autodetection.
-In order to reenable autodetection, you
-have to issue an \fBFDCLRPRM\fP.
-.TP
-.B FDGETDRVTYP
-returns the type of a drive (name parameter).
-For formats which work
-in several drive types, \fBFDGETDRVTYP\fP returns a name which is
-appropriate for the oldest drive type which supports this format.
-.TP
-.B FDFLUSH
-invalidates the buffer cache for the given drive.
-.TP
-.B FDSETMAXERRS
-sets the error thresholds for reporting errors, aborting the operation,
-recalibrating, resetting, and reading sector by sector.
-.TP
-.B FDSETMAXERRS
-gets the current error thresholds.
-.TP
-.B FDGETDRVTYP
-gets the internal name of the drive.
-.TP
-.B FDWERRORCLR
-clears the write error statistics.
-.TP
-.B FDWERRORGET
-reads the write error statistics.
-These include the total number of
-write errors, the location and disk of the first write error, and the
-location and disk of the last write error.
-Disks are identified by a
-generation number which is incremented at (almost) each disk change.
-.TP
-.B FDTWADDLE
-Switch the drive motor off for a few microseconds.
-This might be
-needed in order to access a disk whose sectors are too close together.
-.TP
-.B FDSETDRVPRM
-sets various drive parameters.
-.TP
-.B FDGETDRVPRM
-reads these parameters back.
-.TP
-.B FDGETDRVSTAT
-gets the cached drive state (disk changed, write protected et al.)
-.TP
-.B FDPOLLDRVSTAT
-polls the drive and return its state.
-.TP
-.B FDGETFDCSTAT
-gets the floppy controller state.
-.TP
-.B FDRESET
-resets the floppy controller under certain conditions.
-.TP
-.B FDRAWCMD
-sends a raw command to the floppy controller.
-.P
-For more precise information, consult also the \fI<linux/fd.h>\fP and
-\fI<linux/fdreg.h>\fP include files, as well as the
-.BR floppycontrol (1)
-manual page.

-.SH NOTES
-The various formats permit reading and writing many types of disks.
-However, if a floppy is formatted with an inter-sector gap that is too small,
-performance may drop,
-to the point of needing a few seconds to access an entire track.
-To prevent this, use interleaved formats.
-.P
-It is not possible to
-read floppies which are formatted using GCR (group code recording),
-which is used by Apple II and Macintosh computers (800k disks).
-.P
-Reading floppies which are hard sectored (one hole per sector, with
-the index hole being a little skewed) is not supported.
-This used to be common with older 8-inch floppies.
