In case you missed an article on X-Ways Forensics Imaging (page 40), you can download a free copy of the issue of eforensicsmag here: http://eforensicsmag.com/jumpstart-3-free/
The article is an overview of imaging with X-Ways Forensics, which is covered in more detail in the XWF Guide. If you haven’t bought the guide yet and are on the fence on whether XWF is right for you, check out the article on the one feature of imaging and I am sure you will not be on the fence anymore.
