Free, but limits the protected partition on the pen drive to only 2GB The rest of the drive is accessible as usual.

If you are looking for encryption try http://www.truecrypt.org

 

depending on what size flash memory you want then it may be easier buying a biometric/fingerprint flash drive, i have a couple of these and they work brilliantly
