    The included SanDisk encryption program worked, but I chose to delete it, since it encrypted each individual file -- which is great for security, but I would have preferred to do my encryption at the folder level (If it had that capability, it certainly wasn't obvious to me). Other than that, fine product. I feel much more secure about my data now that I'm not having to rely on a spinning disk in a heavy, easily drop-able drive.
