I just tried my seek test on NTWS 4.0 - resulting file is zero-filled...

#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>

main()
{
	int fd;
	int i=0;

	fd = open("seek.tst", O_CREAT| O_WRONLY|O_BINARY, 0666);
	write(fd, &i, 1);
	i++;
	lseek(fd, 4096, SEEK_SET);
	write(fd, &i, 1);
	i++;
	lseek(fd, 8192, SEEK_SET);
	write(fd, &i, 1);
	i++;
	lseek(fd, 16384, SEEK_SET);
	write(fd, &i, 1);
}
