I'm not quite sure if this will do what you want, but you can use TrueCrypt (free disk encryption software from <http://www.truecrypt.org/> ) to create an encrypted partition on an external drive.

Is there any suggestion for a better method?
You need to supply a password to mount the partition, but once it's mounted, reads and writes are encrypted/decrypted on-the-fly. I ran some brief tests with QRecall and it seemed to work just fine with an archive on an encrypted partition. It is a little slower, because of the on-the-fly encryption.
Once the partition is unmounted, no one can access anything on it without the password.
