With your OS X install disk in the optical drive, press and hold down the C key while powering up your Mac to boot from the CD or DVD. After it boots from the upper part of the screen select the disk utilities. Format the drive using the "write zero" option (This will map out any bad sectors son information isn't written to them.) You should be able to install your operating system after the drive is properly formatted. You may have to format the hard drive in target mode.
