For removable HDD (if it needs to run in parallel during use of the data):
use
an encrypted file system.
For DVD (or removable HDD if used as if it was a removable backup medium)
backups: simply encrypt the backup.
The former is a bit problematic - whenever the harddisk is mounted a
passphrase needs to be enetered (or a dongle plugged in) in order to access
it - if the mounting / booting shall happen without human intervention, it
is
not doable
The latter can be fully automatized by encrypting the backup with an
asymmetric algorithm - you can safely leave your *public* key on the machine
that backs up, as long as you keep your *private* key locked up e.g. in a
safe. You can use free and scriptable software like gpg ("GnuPrivacy Guard")
for this purpose
Horst
