NAME
       createhdf -- Create a blank IDE hard disk image in .hdf format

SYNOPSIS
       createhdf [ -c ]	[ -s ] [-v version] cylinders heads sectors file

DESCRIPTION
       createhdf  creates a blank image	of an IDE hard disk in .hdf format for
       use with	Sinclair ZX Spectrum emulators.

OPTIONS
       -c     specifies	that the .hdf image should  be	created	 in  `compact'
	      mode, where only the low byte of every word is stored in the im-
	      age. This	is useful for saving space if the hard disk  image  is
	      for  use	with  an interface which accesses only the low byte of
	      every word.

       -s     specifies	that the .hdf image should not be created as a	sparse
	      file.  Normally,	createhdf will attempt to create the hard disk
	      image as a `sparse file',	where the operating system knows  that
	      the  file	consists mostly	of zero	bytes and fills	those in with-
	      out using	any space in the  file.	 This  option  disables	 this.
	      (There's	nothing	 `magic' about this: if	data is	written	to the
	      file, it will take up space just like any	other data; it's  only
	      empty space which	is synthesised by the operating	system).

       -v version
	      specifies	 the version of	.hdf image to be created. Valid	values
	      are `1.0'	for a version 1.0 file and `1.1'  for  a  version  1.1
	      file. Defaults to	creating version 1.1 files.

       -h, --help
	      give brief usage help, listing available options.

       -V, --version
	      output version information.

       cylinders
	      specifies	the number of cylinders	in the image.

       heads  specifies	the number of heads in the image.

       sectors
	      specifies	the number of sectors in the image.

       file   specifies	the file to which the image should be written.

BUGS
       None known.
