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

"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."
Excellent point!! I can testify to this, having worked at Segate, in a
clean room, assembling hard drives ;-)
