I'm planning on re-partitioning my existing 160gb sata drive this weekend into 2 partions, 1 for the OS and 1 for data. I then will image the OS partition so that I have a backup in case of disk failure that is easy to reinstall. I will use Norton Ghost and would like to get the image as small as possible. Are there any folders/files that are surplus to requirements that i can safely dispose of prior to creating the image? Ideally it would be good to get the image size down small enough to fit on a dvd, is this easily acheivable? Thanks.
