Seriously, unless the disk is damaged or you are installing incorrectly, that can not happen.
Format the drive (no you don't need to do a long format) and ensure you install a fresh copy on a fresh NTFS partition.
If you run into the same issue and your CD is not scratched I'd highly suggest trying another HD or going out and purchasing a new one.
Storage devices are cheap now days and if you wanted to go crazy (like myself) you could get a velociraptor!
