Is it normal to have big HDD load/usage and everything is slow on pc(openning other programs) while installing large games(AC4), copy large amount of data (e.g. 30gb from d partition to c) or when you add a large torrent to utorrent and you start downloading it then is also big HDD load/usage.I tested Hdd with hdd tune and everything is ok. Is everything ok with my pc?
