I bought a Hitachi 500GB HDD (7200rpm) just over a month ago (29/08/12)
This morning I turned on my computer and it started normally (booted in 25.6s)
I had some tabs opened in Opera then I heard this clicking noise from the hard drive, my computer started to move slowly and I shut it down for a few minutes and then turned it back on.
It started to stick/move slowly and didn't get passed loading Windows. I turned it off again and waited a while and turned it back on again and it's working fine and no clicks.
I ran HD Tune to diagnose the problem further and Error Scan said it had no problems.
However, I saw this in the Health tab -
Health Status - Warning
Re-Allocated Sector Count and Re-Allocated Event Count both say warning as well.
I live in Trinidad (Caribbean) so the average temperature is 33*c but my house is air conditioned, could the fluctuation in temperature (when the a/c is not on) be a cause?
There have been frequent power outages recently and the computer wasn't shut down properly the times it happened. Could a bad/failing PSU be the cause of this? I have another 500GB (Seagate 7200rpm) which I also run but disconnected since to isolate the problem.
Also, I downloaded a 40GB file over the period of a week and left computer on for that time. I mostly do word processing, watch movies, play games, download and stream videos.
