Power: Can someone explain to me how to connect this hard disk to the power? My Corsair power supply has the usual SATA power plugs, which are plugged in next to each other at the back of the hard disk (one narrow and one wide). Now, however, it has a second power connection on this hard disk, but I can't find any plugs for it for the life of me. I have now simply used the SATA plugs and the disk runs. What is the 2nd power connector for and how can it be connected? Thanks in advance for clarification.
