Webshark,

Drive Image makes a complete image of the HD and compresses it. You can select low, med, or high. It doesn't compress enough to fit on a zip disk though. It will span CD's if you have a burner. I just save the image file to another partition on my hard drive and also burn a basic image to CD with drivers, browser, ZA and a few other basic things installed.

My basic image is about 495 MB and my most recent (just of my C: drive) is 650 MB, using high compression.

It will also copy the entire contents of your drive to another HD if you ever upgrade.
