My main question is, when an HDD is first put into an PS2, does the HDD in anyway register itself to that PS2 alone, meaning it _cannot_ be used with a different PS2? My main purpose here is to get final fantasy online working, because my ps2 has DRE disc read error, and cannot read the "PlayOnline" disc that comes with it which is required to install final fantasy online, though my friend offered to install it on _his_ ps2, and then switch out the HDD to my ps2, would it still work?, does anyone know if there is any way to get around this? I have tried very hard using the "turning the little white gear" method, and also putting tape onto the disc to make it heavier, but to no avail I never can get my PlayOnline purple bottom disc to boot making it impossible to install FF. T__T; so if anyone knows a way to get around this, please respond!!!
