@Checkmate: My point was that after just disconnecting two of them, you'll still be able to access all the data and so it doesn't really matter if those two were just pulled out or destroyed in that sense. Or at least I think so :P
It should also technically fill a new HDD with the same data that was stored on the undamaged and unplugged HDD. OR it requires you put it back? Either way it's very interesting so thanks for the info^^
And night Terumi and Nemuru~
