When I follow Apple's instructions for preforming a complete erase and reinstall on a FileVault 2 encrypted SSD machine, and choose a high level of security for the erase, I get an error, and the process (apparently) completes instantly.
Did this securely erase my FileVault machine? If not, what should I have done; and what (if anything) can I do now (that I've "erased" my machine)?
The scenario: I wanted to securely erase a FV-encrypted SSD (to hand of the machine to another user; I will be using the same FV password on a new machine, I have no recovery key), but my attempt seemed to have failed quickly with an error (though the option for secure erase was enabled). Even so, the drive seemed to have been "erased" in some form anyway (there was no OS to boot into; though wifi was still working after the "erasure", so something was left) and I proceeded to reinstall OSX.
I don't know where I am now though. Is this the correct procedure? Have I performed the "official" (secure-as-it-gets) erase procedure for a FV-encrypted SSD after all (error message and nearly instant completion notwithstanding)?
