I stumbled again at this post; "the key cannot be extracted"??? Why on earth would a portable drive need to store the decryption key for its data, however protected?? Actually I've never looked before into "encrypted drives" and I don't know what do they do or what purpose exactly do they serve, I must have written that thinking about HSMs and other signing devices. It does seem indeed that at least those Kingston drives do not store the encryption key (actually, they store it but encrypted with the password). I'm not sure what purpose do the FIPS certification and all those physical protections serve, then.
