just bought new hard drive (2tb) formatted it and was going to transfer OS and all data on main drive to new hdd. however i used AOMEI partition assistant to transfer the OS from old hdd to new hdd, finish the transfer and my new hdd is non existent cant see it in disk management or my computer or bios boot menu. i have no idea what ive done here. all i wanted to do was transfer old hdd data over to new including OS as old hdd is slow i feel and only 500gb. Many Thanks
