Good day all,
Another issue with many hard-drive cameras is that the hard-drives within use a mechanism with "air bearings".
These are slip bearings held by air pressure (no balls).
Basically, what this means is that the air density affects the hard-drive.
Normally, at elevations below 7,000 - 8,000 feet MSL, this is not a problem, even for storm chasing in Colorado's Palmer divide.
In mountainous areas, however, this becomes a problem ... Especially above 10,000 feet.
Same for skydiving, the Hard-Drive camera is affected by the lower pressure.
When the air bearings are affected by altitude, the hard-drive spins down (resets) and the camera shuts down.
