In unix, disks are files like any other file. So if your programming
language allows you to read and write files, it allows you to read and
write disks.
Just write the equivalent of:
int fd=open("/dev/hda",O_RDWR,0);
if(0<==fd){
check_errors(lseek(fd,SECT_SIZE*sect_num,SEEK_SET));
check_errors(read(fd,buffer,SECT_SIZE));
modify(buffer);
check_errors(lseek(fd,SECT_SIZE*sect_num,SEEK_SET));
check_errors(write(fd,buffer,SECT_SIZE));
close(fd); }
and be sure to have the access rights on /dev/hda (and to know what
you're doing!).
