Thanks for taking your time to answer my question. My hdd is not detecting in bios. I want to give it to RMA. But the bios version is require to register my hdd on their site. And it is marked mandatory (*marked). I am from Mumbai-India. And my hdd is Hitachi and there are few service center and I don't even know if it is near. I checked on Google and found WD (Western Digital) are taking Hitachi RMA in there service center. So I was trying to email to them if they are taking my hdd. And when I try to logged my complain on their site it want all the info like S/N, Model #and bios version.
