I don't know that utility but I find that the best way to save and restore complete hard drive images is not to put them on removable media (CDs/DVDs) but on another hard drive. It can be an internal or external drive that's large enough to accommodate the image file. The program I use is one I paid for (Acronis True Image) and the image file created is about 40% as large as the total data size on the hard drive. You can keep the image on internal or external devices. I use both. To restore the image, you must use the same program that you used to create it. This means that if you suffer a hard drive failure, you cannot restore the image from an installed program on that dead hard drive. You will need to create a bootable CD of the imaging utility. The program I use does install on the hard drive but also creates a bootable disk which I can use if I need to replace a defective hard drive or move to a larger one. One nice feature of the program I use is that I can extract individual files or folders from image files if they've become corrupt, lost, etc. I've found HD images to be an important, if not essential, part of a backup plan. Good luck.
