The next window also has check boxes that allow the user to verify the image after it is created and there is also an option to create directory listings of all files in the image.

The window shown above is where you choose what format you want to save the image in, you have a choice of Raw (dd), SMART, E01, or AFF. For this case Raw (dd) image format was chosen because this format is supported by most forensic analysis tools including EnCase, and FTK.

The next screen prompts the user to enter information about...
