Hi guys. I have a 1tb samsung harddrive. For 3 months now its been making the spinning up noise. When watching series from drive and i click on next show the drive hangs and spins up again and only after that it will start playing. The feature for shutdown harddrive when not in use is switched off stating never. Is this drive on its way out. I think its about 4 years old already. I have run diagnostic software and its stating harddrive is healthy. But this problem happens everyday the whole day. Any advice please?
