    Hi all

    I've FileVaulted my internal disk. Under Lion this is a really simple background operation - it's great.

    I also want to FileVault 4TB of external FW800 drives, but it seems the only way to do that is with Disk Utility while wiping them.

    But I obviously can't wipe all my data, and really don't want to buy a new enclosure & shuffle all the data onto new, FileVaulted disks.

    Is there any way around this? Ideally I'd like to do something similar to what I did with the internal disk - just enable FileVault & let it do its thing in the background ...

    Thoughts?

    Make sure you have everything essential backed up, then search the forums and web for "diskutil coreStorage convert".
    You could have a look at this thread for example.
