@wohali Hah, reminds me of this Stack Exchange thread I found while researching the "WD Security" feature of my new external drive: https://security.stackexchange.com/questions/44730/how-secure-is-wd-mypassport-lock
An informed user makes reasonable inferences about what the feature actually does, and its effectiveness, based on available information...and two years later, said inferences are verified by researchers.
