Alright, So to avoid buying new hard drives one after another I decided to do something about it. I had this annoying vibrations in the palm rest area that spread to the left side also. Of course I did not want to part with the speed of 7200rpm HDD so I decided to take a step forward. I have Unibody MBP 2010. What you will need: Phillips screwdriver, elastic eraser, some paper napkin or something like that. Also a small hex screwdriver, however I could never find such a small hex screwdriver to twist those HDD mounting screws. 1. Unscrew the back panel of your MBP (MAKE SURE U SWITCH IT OFF AND UNPLUG THE POWER CORD BEFORE U PROCEED!!! 2. Remove the back cover. 3. Locate the HDD in the lower left corner ( i suppose you have you MBP flipped). 4. If you want you can take our ur HDD and make sure that your mounting screws are well screwed on the sides of the HDD. 5. Put ur HDD back in place make sure it is secured with that special black piece of wood with 2 screws. 6. Now look closely on the gaps between HDD and MBP CASE from UP bottom and RIGHT (close to the battery) this is where you need to stuff something into those gaps to makes sure that HDD is well secured in it's position. NOTE: DO NOT PUTT ANYTHING FROM THE SIDE OF SATA JACK 7. I found that eraser is the most suitable material to absorb vibrations. So I had to cut it in pieces in fit it around the HDD. 8. Now you will most likely notice that the gap on the right is very narrow so here you would need something like paper napkin or a tissue, this place in particular was causing vibrations on my MBP 13 2010. I used a small screwdriver to stuff that place with soft material as it is too narrow to be done with hands. P>S Obviously the eraser has to be slightly wider than gaps otherwise ur HDD will keep vibrating. 9. Make sure you screw everything back. 10. Put the back panel in place and screw it firmly in place. You're done. I know this is a really weird way to fix it, but hell at least it works and you don't have to listen to people who say get used to it.
