I am pleased with a product call TrueCrypt (www.truecrypt.org).
"Truecrypt is free open-source disk encryption software for Windows
XP/2000/2003 and for Linux", and I have been using it without any
problems for quite a while. From their home page:

Main Features:

    * Creates a virtual encrypted disk within a file and mounts it as a
real disk.

    * Encrypts an entire hard disk partition or a device, such as USB
flash drive.

    * Encryption is automatic, real-time (on-the-fly) and transparent.

    * Provides two levels of plausible deniability, in case an adversary
forces you to reveal the password:

      1) Hidden volume (steganography – more information may be found here).

      2) No TrueCrypt volume can be identified (volumes cannot be
distinguished from random data).

    * Encryption algorithms: AES-256, Blowfish (448-bit key), CAST5,
Serpent, Triple DES, and Twofish.
      Mode of operation: LRW  (CBC supported as legacy).

    * Based on Encryption for the Masses (E4M) 2.02a, conceived in 1997.
