So all you need to do is never let the air seal break.
Older drives would be incredibly dangerous.
Let's not get carried away here. A few cubic inches of hydrogen wouldn't pose much of a threat.
When I was a teen, I used to play with hydrogen quite a bit. I once filled a small (1 quart, maybe) plastic bag with it, plus some air. I laid it on the cellar floor, and tossed on a lit match. I was surprised at how loud the bang was. (Scared my mother, upstairs, badly.) The concrete floor wasn't marked.
I imagine that the drives would be filled with helium for engineering purposes, rather than safety. Helium has a much higher thermal conductivity than air; I don't know how H2 compares.
