Some of the newer flash drives include U3 technology...they have software built-in that can enable you to run U3-compatible software right from your flash drive. (Portable browsers, word processors, and encryption utilities leave virtually no trace on the computer you used so it's perfect for anonymity.)

The downside is that the platform is somewhat buggy...if the local administrator has prohibited the usage on unauthorized software the drive may encounter errors after being inserted and in some cases even crash the system. Specifically, Verbatim Store-n-Go may require you to have local administrative privileges.

A workaround is to disable Autoplay on that drive or the computer as a whole, preventing the U3 software from launching automatically and forcing it to act as a standard flash drive.

Hope this helps and if it's not a U3 drive let us know.
