I plugged my HD into my PC and used WinHIIP to transfer some games to it. After plugging it back into my ps2 HDL no longer could find a HD. I took it out put it into my cpomputer and used WinHIIP to scan to see if any repairs were needed, it said everything was good. So i just plugged it back into my ps2, yet it still wont find the HD. any idea what may be wrong?
