Things You'll Need
Instructions
Unplug your PS2 from the electrical outlet. Remove controllers and memory cards from the console.
Detach the expansion-bay panel on the back of the console. Insert the screwdriver into the slot on the top of the expansion bay and pop out the cover.
Connect your HDD to the PlayStation network adapter. The connection tabs fit together only one way.
Insert the HDD and Playstation Network Adapter into the expansion bay on the back of the PlayStation 2. Gently push them into the bay.
Using the screwdriver, gently turn the mounting screws on the bottom of the network adapter to mount the HDD into place. Turn only until it is tight--do not overtighten, as you can damage the system and the network adapter.
