Pen drives are wonderful aren't they... I have two 1GB ones that I use (1 for work, 1 for personal) and it's brilliant to carry that much data around.
However, what if I lost it, or worse it got stolen ?
What does everybody do to secure the data on their pen drives ? I know you can buy ones with encryption built in (I think) but it's not something you think about at the time, is there anything you can do afterwards other than password locking files, putting files in password zip files etc. ?
