I read the installation guide at http://ps2drives.x-pec.com/?p=ps2_installation and thought it would be easy. I got my hard drive today and when I took apart my network adapter I noticed it was slightly different than the one in the tutorial. After taking the plate off, it has star type screws to hold the ports that fit into the HD. I bought this Network adapter used and it came with a 2.5 version disc. I have another network adapter that I have installed using a Seagate HD that worked perfect. I took this network adapter apart to see if it would work, but it is just like the one I purchased, and I bought this network adapter when it first came out. Can anyone help? Is there a guide to modify this type of network adapter? By the way both are official Sony Network adapters.
