Rohos Mini Drive is another security product I have come across, but one that is relatively easy to setup. AND you don't need admin rights for this one, so you should be safe in most environments using this software.

It also been independently tested and got a pretty good review at cnet.

Rohos Mini Drive creates hidden and encrypted partition on the USB flash drive memory and you can work with the files on the hidden partition without opening a special program.

Give it a go...
