Please log in for more thread options I beg to differ with you. If you did what you claim, the drive was not
truly protected by the mechanism that we are talking about. That
mechanism is OS independent, works before any OS boots on the machine,
and the drive is totally invisible and inaccessible until the correct
password is entered.
You were dealing with a different protection mechanism than that which
we are discussing.
