i'll inline the source since it didn't came through..
#include <stdio.h>
#include <fcntl.h>
#include <err.h>
#include <sys/types.h>
#include <sys/ata.h>
int main() {
struct ata_params ap;
int fd, i;
if((fd = open("/dev/ad0", O_RDONLY)) == -1) {
err(1, "error opening /dev/ad0");
}
if (ioctl (fd, IOCATAGPARM, &ap) == -1) {
err(1, "error executing ioctl");
}
printf("Model: ");
for(i = 0; i < 40 && ap.model[i] != '\0'; i++)
printf("%c", ap.model[i]);
putchar('\n');
printf("Revision: ");
for(i = 0; i < 8 && ap.revision[i] != '\0'; i++)
printf("%c", ap.revision[i]);
putchar('\n');
printf("Serial: ");
for(i = 0; i < 20 && ap.serial[i] != '\0'; i++)
printf("%c", ap.serial[i]);
putchar('\n');
return 0;
}
Cheers,
Vik
