Except for the helium-filled ones, they aren't sealed; there is a very fine filter that equalises atmospheric pressure. (This is also why they have a maximum operating altitude --- the head needs a certain amount of atmospheric pressure to float.)
- bitexploder 2y agoHow does the helium stay in if it is not sealed? I am not familiar with hard drive construction, but helium is notoriously good at escaping.
- lorax 2y agoI think he meant in general drives aren't sealed, except the helium ones are sealed.
- bitexploder 2y agoOh, I see. Makes sense. I wonder if dust really can infiltrate a drive? Hmm.
- gosub100 2y agoI"ve heard 2nd-hand that helium will slowly escape (over a period of years).
- aaronmdjones 2y agoYup, this is why the label will say something along the lines of "DO NOT COVER DRIVE HOLES".
