In addition, many others have contributed indirectly, and without their efforts and support, this book would not have come to fruition. That said, many are people deserving of my gratitude, and my intent here is to acknowledge them all. I would like to first thank Maureen Adams, former Wiley Acquisitions Editor, who brought me on board with this project with the first edition and tutored me on the fine nuances of the publishing process. I would also like to thank Jeff Kellum, another Wiley Acquisitions Editor, for his work on the second edition. Jeff guided me through the second edition, keeping me on schedule and helping in many ways. I would also like to thank Stef Jones, Developmental Editor. Stef allowed me to concentrate on content while she handled the rest. In addition to many varied skills that you’d normally find with an editor, Stef has a strong understanding of topic material, which helped in so many ways. In addition, with several hundred screen shots in this book to mold and shape, I know there is a graphics department at Wiley deserving of my thanks. To those folks, I say thank you. A special thanks goes to Jon Bair of Guidance Software, Inc. In addition to being a friend and mentor of many years, Jon was the technical editor for the first edition. An equally special thanks goes to Dave Arnett, also of Guidance Software. Dave is a master instructor for Guid- ance Software and was the technical editor for the second edition of this book. They both worked diligently, making sure the technical aspects of both editions are as accurate and as complete as possible. Sitting behind the scenes on this project at Guidance Software was Bill Siebert. In addition to being a friend and colleague, Bill is the director of customer relations for Guidance Soft- ware. Bill was, with both editions, the facilitator, fixer, go-between, and, at all times, a guiding hand. Thanks, Bill! Many thanks go to William Wei, who made many contributions to the first edition end of chapter tests, as well as some of the Real World Scenarios. Some of those contributions have been carried forth into this edition. Thank you, Will! The study of computer forensics can’t exist within a vacuum. To that extent, any individual examiner is a reflection and product of their instructors, mentors, and colleagues. Through them you learn, share ideas, troubleshoot, conduct research, grow, and develop. Over my career, I’ve had the fortune of interacting with many computer forensics professionals and have learned much through those relationships. In no particular order, I would like to thank the following people for sharing their knowledge over the years: Keith Lockhart, Ben Lewis, Chris Stippich, Grant Wade, Ed Van Every, Raemarie Schmidt, Mark Johnson, Bob Weiter- shausen, John Colbert, Bruce Pixley, Lance Mueller, Howie Williamson, Lisa Highsmith, Dan Purcell, Ben Cotton, Patrick Paige, John D’Andrea, Mike Feldman, Mike Nelson, Steve Mahoney, Joel Horne, Mark Stringer, Dustin Hurlbut, Fred Cotton, Ross Mayfield, Bill Spernow, Arnie “A. J.” Jackson, Ed Novreske, Steve Anson, Warren Kruse, Bob Moses, Kevin Perna, Dan Willey, Scott Garland, and Steve Whalen. Every effort has been made to present all material accurately and completely. To achieve this I verified as much information as possible with multiple sources.
