    I have read here that the best way to securely remove any personal information from the Air SSD drive with Lion is to encrypt the disk with FileVault, then "trash the keys". Exactly how is that done?

    In the Apple Lion description page, they also recommend using FileVault, and then they state:

    Instant wipe
    With FileVault 2, instant wipe removes the encryption key from your Mac instantaneously, making the data completely inaccessible. Then your Mac performs an entire wipe of the data from the disk.

    I am unable to find any command to perform this task. Where do you locate it and how do you do this?

    Thanks for the help...

    Perhaps it's the remote wipe feature of Back-to-my-Mac.

    Hmmm ... thanks, I hadn't thought of that, although that seems pretty obscure for a Lion "feature". ;)

    I would have thought a "instant wipe" command might have been included in the recover boot menu or in that version of disk utility. Perhaps it is something they didn't get finished for the release?

    Thanks,
