MyBook Essentials - 2 reasons not to buy

You can try finding a circuit board on Ebay. This might help a little in matching them up  http://community.wd.com/t5/Off-Topic-Discussions/Bridge-Boards/td-p/353839 The only person who knows much about these boards is fzabkar. You can try searching his posts. I won’t buy an excrypted drive either unless it was for something that needed that security level.
