Not really. Full disk encryption using Pointsec&#x2F;other commercial offerings, or as you typically do it on Linux with LUKS+dmcrypt, asks for the passphrase before the OS has loaded any Firewire drivers. In which case a fully shut-down computer is not vulnerable to this attack, ie. you have protection against evil maids, thieves, FBI etc.<p>But with Bitlocker, it only requires a password at Windows login, and by then all the Firewire etc. drivers are up and running. So you have no protection for computers that are stolen&#x2F;seized by law enforcement.
