Yes! That was what I wanted to see you write that the problem moved with the drive. Before you think the drive is the problem the next move is to take your time and see how your BIOS settings are set, write them down and see how they look compared to your brothers settings. If nothing there shows any different then we'll move to the next step but I do like your idea of rolling your driver to an older version, I found 10.3 to be the most compliant.
