about electronically stored information. Despite its daunting complexity, all digital content—photos, music, documents, spreadsheets, databases, social media and communications—exist in one common and mind-boggling form: More than 95% of the information in the world exists on electromagnetic hard drives as an unbroken string of ones and zeroes, memorialized as impossibly tiny reversals of magnetic polarity. These minute fluctuations must be read by a detector riding above the surface of a spinning disk on a cushion of air one- thousandth the width of a human hair in an operation akin to a jet fighter flying around the world at more than 800 times the speed of sound, less than a millimeter above the ground…and precisely counting every blade of grass it passes. That’s astonishing, but what should astound you more is that there are no pages, paragraphs, spaces or markers of any kind to define the data stream. That is, the history, knowledge and creativity of humankind have been reduced to two different states (on/off…one/zero) in a continuous, featureless expanse. It’s a data stream that carries not only the information we store but all of the instructions needed to make sense of the data, as well. It holds all of the information about the data required to play it, display it, transmit it or otherwise put it to work. It’s a reductive feat that’ll make your head spin…or at least make you want to buy a computer scientist a beer. These exercises and readings are designed to get you thinking about the fantastic journey data takes from its simple, seamless existence as an endless stream of ones and zeroes to the seemingly-endless variety of documents, communications, records and formats that confound us in e-discovery. These exercises and readings will help you answer such questions as: 1. How do computers store data? 2. What are the differences between common storage media? 3. How do computers encode data? 4. How do computers use binary signatures and file extensions to distinguish file types? 5. How are foreign languages encoded differently from English? 6. What’s the difference between system and application metadata? 7. What are the seen and unseen elements of an e-mail message? 8. Where does deleted data go, if it’s not really gone? 9. How are deleted data recovered? 10. How do search tools and review platforms operate? 11. What is forensic imaging? 4 12. What are load files, how are they used and what challenges do they present? 13. What impact do alternate forms of production have upon cost and utility? 14. What are the key elements of an effective, cost-effective and defensible legal hold? 15. What should occur at meet-and-confer? Some of these questions may seem hyper technical and far removed from the day-to-day of e- discovery and the practice of law; but, they serve as essential building blocks in a solid foundation for development of practical skills. The absence of a solid foundation ultimately limits how high you can go. Thank you for enrolling in this class. Together, I hope we can make it a course you will value all your life.
