I have Samsung Spinpoint F3 1tb hard disk. When I installed that to my computer then I noticed some vibration on my desk. I recognized that this is from the hard disk. To confirm that, I disconnected the hard drive from it and after that when I booted the system then it does not make any such vibration. This vibration only comes for about 1 to 2 seconds. Can you tell me that what is the problem with this and is there any solution by which I can resolve this? Thank you.
