I currently have a Lexar JumpDrive Secure 256mb, which works well on both my PC and my mac mini. It comes with software that allows me to create a partition that is password protected. I looked at some of Lexar's newer flash drives, specifically the Lightning, but they don't list OS X as being supported. I know I would be able to use it as just a regular flash drive but I want the password protected volume. What kind of flash drive do you have? Anyone have any a recommendation for one that works with OS X to provide a secure volume?
