My partitioned flash drive needs your help with password protection.

    So, here's a description of the flash drive in question:

    It's a 2 GB Sandisk Cruzer Micro. It's been partitioned into two 1 GB partitions with Disk Utility, one formatted with HFS+ for Mac and the other with FAT for Windows.

    What I'm looking for is some program to password-protect both partitions, so that when someone tries to access one of them they are prompted for a password. Whatever program(s) does this must be able to run completely off the USB stick, without any need for installation of anything on the computer the flash drive is plugged into.

    Any suggestions?

    If this is just for Macs, I'd consider using the Disk Image utility because it can create encrypted images, both single files, and sparse images.

    If this is for both Macs and Windows machines, and you can't use TrueCrypt's Traveller Mode feature, this is difficult, because there are USB flash drives that have U3 software with password protection, but they only work with Windows, and not Macs.
