I have the Sony Hard drive here, I soft-modded my Ps2 and I had some problems with a Hard Drive, so I decided to change the hard drive for the official Sony one. Iv put all the games I wanted on my Hard Drive with Winhiip. My Ps2 does not detect my hard drive. But when I try it on my friend's Ps2 ( Memory Card, Psx Game and everything....) It works fine, I can play. What is the problem, anyone can help? I only have my friend's ps2 for a while....Thanks all!
