Is there a way to encrypt or password protect such a harddrive/

If the same systems would work the Macs too it would be great

Some kind of prep would be necessary if the Windows box is not
already set up for encryption.

I haven't tried using the disk's encryption system with Linux. I
don't feel it's ready for primetime yet and there is the question of
trust wrt backdooring or a vendor's key allowing unauthorized access.
Vendor implementations seem to block it's use with Linux as well.

It may be possible to use Truecrypt or Realcrypt without installing
it on the windows box.

Alternatively, booting from a Linux live CD or USB stick would avoid
having to change the Windows system. I would usually recommend
Knoppix since it seems to work on more systems than Ubuntu and
derivatives but IIRC truecrypt/realcrypt is not in the latest

It's going to take a few hours to set up a large disk for use with
Truecrypt. 500Gb USB HD takes about 3.5 hours typically on a
4GHz/4Gb box running X and Linux and doing nothing else. That's the
main drawback of using Truecrypt over hardware disk encryption.

Thanks jd and everyone else who've chipped in - Truecrypt/Realcrypt seem
to be getting the majority of votes, but for now, I'll quite likely go
with ZIP-files with password.
There's built-in support for those as of Win XP, and I expect they won't
be an issue an Macs either. It may not be the strongest/most secure
solution, but it's sufficient to ward off anyone who accidentally gets
hold of the data.
