Hello

I have a WD Caviar Black HDD that's responding extremely slowly for some reason, even reformatting installing windows 7 it takes about 4x longer than my WD Caviar Green, do you guys think it's a hardware issue and I should replace my drive? Have anyone experience something simular issues? Many thanks in advance.
