all. HDs are air tight.
Not any hard drive that I have ever used. Take a look and you will see
an air hole in them usually on the side. More info is at the link below.

"Hard disk drives are not airtight. They have a permeable filter (a
breather filter) between the top cover and inside of the drive, to allow
the pressure inside and outside the drive to equalize while keeping out
dust and dirt. The filter also allows moisture in the air to enter the
drive. Very high humidity year-round will cause accelerated wear of the
drive's heads (by increasing stiction, or the tendency for the heads to
stick to the disk surface, which causes physical damage to the disk and
spindle motor). You can see these breather holes on all drives -- they
usually have a warning sticker next to them, informing the user not to
cover the holes."
