How do I encrypt a OS X Tiger drive?

[MacBH928]

I have a 2002 iMac g4 that I retired. I am storing it but I want to encrypt its Hard Drive. Here is my issue:

1)I know that FileVault exists since Panther, but my iMac runs Tiger and I heard FileVault pre LION was bad or insecure?! How can I encrypt that hard-drive?

2)My iMac came originally with os 9 partition, if you launch from os 9 partition you can see all the files on the OS X partition(Even though the OS X needs a login password). How can I encrypt the os 9 partition too?

3)I have the whole drive backed up using Carbon Copy Cloner to an external disk, it has both the OS 9 system files and the OS X Tiger. Can the current version of CCC or TimeVault encrypt that external drive? Or it will not work because its an older OS?
If not , how can I encrypt the external drive?

Thank you very much

You'll have to use some third-party implementation.

You could try TrueCrypt, which is open-source disk encryption. I think it runs OS X. I doubt you'll find disk encryption for OS 9.
