It allows for equalization of air pressure between the inside and outside of the drive. While it is not a complete pass-through of outside air into the HDD internals, there is a*filter inside the hole that allows the air pressure to equalize.

If the drive were completely sealed, operating at altitudes significantly different from those the drive was manufactured and sealed at, it would cause problems and increase the likelihood of catastrophic failures.

This system works in much the same way as the*Eustachian*tubes that allow our ears internal pressures to equalize, preventing the explosion of our ear drums.

Next time, provide proper citation where you copied this from. I'm willing to bet my KKJ and LP you did not write this yourself.

They even have Youtube videos explaining the "hole in the hard drive" mystery.

I agree... if citing other sources, it is only courteous to provide references rather than make out as if it is one's own intellectual property.

so no fault on the guy who was too lazy to search this himself?
