Unencrypted data represent a risk – whether at work or at home:hackers access your hard disk through the Web. You leave your laptop behind you on the train. Entire PC systems are stolen in a burglary. Another person using your PC accidentally opens private documents. The memory stick disappears without a trace and you simply cannot remember what data you had stored on it. You use your iPod not only for music but also to store data on it.
