SYNOPSIScreatehdf [ -c ] [ -s ] cylinders heads sectors file
DESCRIPTIONcreatehdf 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 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.
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.
