createhdf

createhdf(1)							     Emulators							      createhdf(1)

NAME

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

SYNOPSIS

       createhdf [ -c ] [ -s ] 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 image.
	      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 without 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.

       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.
