|Notice that the two connectors on the Hard Drive are too far apart to fit into the network adapter. What you need to do is this: push the conectors on the network adapter as far apart from each other as possible so the HD can fit.
You should remove the metal plate on the network adapter first. Then, try using a pair of scissors, putting it between the two connectors on the adapter and then opening the scissors to push the adapters far enough apart so you can mount the hard drive. This may be a bit difficult, but it can be done, trust me.
Once you do that, there is another important thing to keep in mind: between the two connectors on the HD that mount to the network adapter are some needles with a pin in them.
It looks like this:
You need to remove the pin and put it into this location
This is called moving it into the "Cable Select" position, otherwise HD Loader will not recognize the drive.
Other than that, the drive works fine. The drive gets really hot and has only 30 GB (~7-9 games)...but hey it works :)
