I use the Lexar JumpDrive Secure.  I have used it for almost 2 years.  It also has built in encryption, as do several others.  If you lose your password, you will never again access your encrypted data, (Don't ask me how I know. <img src="/images/graemlins/blush.gif" alt="" />)
But you can regain access to the entire drive, with help from Lexar.  Then you can hide some more data (keep your password).
