Is it possible to add Truecrypt to an exsisting HDD with data already?

I have my main media HDD that I would like to encrypt, is it possible to add Truecrypt onto this drive WITHOUT formatting it & having to re-copy all of the data back over? It's over 1 TB worth of data, so I really prefer to not have to format & re-copy.

Correct, I want to encrypt the entire drive, as it's only purpose is my personal & media HDD. My OS is on a separate drive.

So your link will do that? I'll check it now

The Ultimate and Business editions of Windows 7 and Vista come with BitLocker, a tool that lets you encrypt your entire hard drive.

HTH

Damn I only have Pro, I knew I should have gone Ultimate!

So is it possible to add Truecrypt onto an already exsisting HDD without losing the data?

Anyone?
