Problem with a Network Adapter and HDD

Hello, recently I bought a network adapter and a Samsung 80GB hard drive (SP0802N) for my PlayStation 2 (model SCPH-50001).

The problem is that when I insert the network adapter with the hard disk, the console does not detect it.

I have tried to format it with uLaunchELF and HDLoader, but they do not detect it.

I hope you can help me.
