Instead of trying to find a program to 'lock' the JumpDrive, how about just using a small program to encrypt the data?
These programs, that I'm about to name, are all under 1Mb (some are Lots! under) and you can place it on the JumpDrive and use it on whatever computer you need the data decrypted on.
All these programs, and their descriptions, I was able to find on NoNags. You can also go to the authors web location for more info and the programs themselves.
NoNags is a very useful site to discover free, or shareware, software that will not nag you to "pay up"

Just purchased a Lexar USB 2.0 256MB JumpDrive. Anyone know of a password protection program (FREE would be ok also), that can be installed on the USB JumpDrive to proctect data? I want something that can be installed on the JumpDrive itself so there's no need to install a program on every computer the drive is used on, that would not be a practical option for me.
