Two issues: 1- I have the Toshiba MK2553GSX 250GB stock hard drive and it is constantly making a humming noise. xBench scores came back just fine (44.71 for Drive/128.43 Overall) so I don't want to switch it out. 2- When i rest my hand on the right side of the trackpad I hear clicking noises. I don't know if the case it hitting the HDD or what. I would like to try using some sort of rubber/cloth pieces to make these noises be less noticeable or go away. What do I use? What is a safe material to put inside my MB to try this trick? What size tools (screwdriver, etc.) do I need to get for this? I want to know what you guys would recommend using... Thanks.
