When i boot up my PC the HD makes a clicking noise. It wont stop unless i down-load something or it starts to spin up. it has been clicking now for about 6-7 min, it just now stopped. would a de-frag help? It just makes me worried that my HD is going to fail sometime. If a HD does stop working, could i get my storage off of it? I almost forgot, its a Toshiba 1tb.
