I wrote about my hard disk noise problem a few weeks back. I have been in a severe depression since then, praying all the time for my hard disk. Yesterday, I was listening to the same noise and I switched off my speakers. There was no noise after I disconnected the speakers. I was kinda surprised by the behavior. I connected speakers again and the noise was back. Eventually I realized that the hard disk was not making any sounds at all. The speakers were the culprits.
This is really a strange problem. Whenever there is a heavy load on the hard disk, speakers start making a noise. Anybody facing the same problem??
