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 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.
- -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.
