    Question Encryption of external hard drive

    What is the correct or safest way to encrypt and password protect an external hard drive? The hard drive has data already on it.

    I can't answer the "best" or "safest" parts.

    What I would do, is set it up with a single LUKS encrypted partition, formatted to ext2, or to ext4 configured to not use journaling. Perhaps there's a benefit in using btrfs instead, but I'm still learning about btrfs.

    To do it that way, you would have to backup the current content of the disk to somewhere else, then restore after setting up the crypto.

    If the disk is also to be used for Windows, then maybe truecrypt/realcrypt would be better than LUKS, and you would probably want to use FAT or NTFS for the file system.

    Why no journal? :-?

    I have the vague impression that I read that it doesn't work or has some
    problem or has not been tested well.

    Personally, I tend to use XFS on those things.
