Every HDD makes some noise...Fact
But! This noise is in fact amplified as HDD touches the metal case of our PC.
So if between our case and the HDD is something else (see rubber strap from a tire inner tube) then the noise is deduced significantly!
Step 1: Materials Needed
Cross cuts from a tire's inner tube (or anything like a rubber strap)
and some screws.
Step 2: Getting the HDD Out and Making Some Space
Now open the PC case carefully and take the HDD out by unscrewing and unplugging.
We need to use 2 5,25 slots (the big ones) so make some space for this.
Step 3: Screwing the Rubbers
If you cant screw them on th Pc case (possible) then thing about securing them with plastic straps (like i did)
Step 4: Final Thoughts
Dont forget to ground the HDD via a conductive cable leading to the case...
And dont shake your PC around UNLESS you secure the HDD or remove it from this fragile position.
