NAME
       dskdump - Sector-level copy from	one floppy or image file to another

SYNOPSIS
       dskdump [-itype TYPE] [-otype TYPE] [-iside SIDE] [-oside SIDE] [-icomp
       COMP] [-ocomp COMP] [-idstep] [-odstep] [-retry	COUNT]	[-format  FMT]
       [-first CYLINDER] [-last	CYLINDER] INPUT-IMAGE OUTPUT-IMAGE
DESCRIPTION
       Dskdump	copies	floppy	discs  or  images, optionally converting image
       types.  Unlike dsktrans(1), dskdump can	handle	discs  with  different
       numbers or sizes	of sector on different tracks.

OPTIONS
       -itype TYPE
	      Determines  which	 driver	 is to be used to read from the	source
	      disc.

	      auto    Select according to the disc image file. This is the de-
		      fault.

	      dsk     Use the DSK (CPCEmu format) image	driver.

	      edsk    Use the extended version of the DSK format.

	      floppy  Use the floppy driver.

	      myz80   Use  the	hard  disk (MYZ80 format) image	driver.	 (This
		      format cannot be autodetected.)

	      cfi     Use the CFI (DOS fdcopy  format)	image  driver.	 (This
		      format cannot be autodetected.)

	      apridisk
		      Use  the	ApriDisk image driver (from the	utility	of the
		      same name).  (This format	cannot be autodetected.)

	      raw     Use the raw driver.

       -otype TYPE
	      Determines which driver is to be used to write to	 the  destina-
	      tion disc. The drivers are as for	-itype.

       -icomp COMP
	      Select the compression method used on the	source disc image file
	      (has no effect when reading a floppy disc).

	      auto    Detect from the first few	bytes of the file. This	is the
		      default.

	      sq      Huffman coded (SQ	/ USQ).

	      gz      Gzipped (gzip / gunzip).

	      bz2     Burrows-Wheeler compressed (bzip2	/ bunzip2).

       -ocomp COMP
	      Select the compression to	be used	on output. Compression methods
	      are as for -icomp, except	that bz2 cannot	be used.

       -iside SIDE
	      Determines which side (0 or 1) of	the source disc	is to be  read
	      from.

       -oside SIDE
	      Determines  which	side (0	or 1) of the destination disc is to be
	      written to.

       -idstep
	      Double-step the source drive (used to read 360k discs  in	 1.2Mb
	      drives). Only supported by the Linux floppy driver.

       -odstep
	      Double-step  the	destination drive (used	to write 360k discs in
	      1.2Mb drives).  Only supported by	the Linux floppy driver.

       -retry COUNT
	      Set the number of	times to attempt a read/write/format  in  case
	      of error.

       -format FMT
	      Do  not  autodetect  the	disc  format;  use  the	 named format.
	      dskdump does not make extensive use of the disc  format;	it  is
	      chiefly used to provide a	guess at the number of tracks to dump.

       -first CYL
	      Start copying at the specified cylinder. Cylinders prior to this
	      will not be formatted or written.

       -last CYL
	      Copy up to and including the specified cylinder.

       -odstep
	      Double-step the destination drive	(used to write 360k  discs  in
	      1.2Mb drives).  Only supported by	the Linux floppy driver.
