I use truecrypt for the same purpose but on USB flash drives. From there
website:
Main Features:
- Creates a *virtual encrypted disk* within a file and mounts it as a
real disk.
- Encrypts an* entire partition or storage device* such as USB flash
drive or hard drive.
- Encrypts a *partition or drive where Windows is installed* (pre-boot
authentication <http://www.truecrypt.org/docs/?s=system-encryption>).
- Encryption is *automatic*, *real-time* (on-the-fly) and
*transparent*<http://www.truecrypt.org/docs/>
.
- Parallelization <http://www.truecrypt.org/docs/?s=parallelization> and
pipelining <http://www.truecrypt.org/docs/?s=pipelining> allow data to be
read and written as fast as if the drive was not encrypted.
- Encryption can be
hardware-accelerated<http://www.truecrypt.org/docs/?s=hardware-acceleration>
on
modern processors.
- Provides *plausible
deniability<http://www.truecrypt.org/docs/?s=plausible-deniability>
*, in case an adversary forces you to reveal the password:
*Hidden volume <http://www.truecrypt.org/hiddenvolume>* (steganography)
and *hidden operating
system<http://www.truecrypt.org/docs/?s=hidden-operating-system>
*.
