Can I password protect a pen drive?

Hi,

I have a pendrive that I intend to backup my documents folder too, and then leave in my desk at work (I have an external hdd I use for back ups as well but that's no good if my house burns down!).

Is it possible to protect the drives contents in some way, either by password protecting it or by encrypting it's contents?

If it helps I use Vista home 32mb.

Thanks in advance
