Interesting. This happened at about 13,000 feet.

I was on a long hike with a young woman recently. We were climbing
Mt.
Whitney from the west side, which requires a long approach of a few
days
hiking. She was using a Canon digital and had a small hard drive with
her to store her images so she could download the card in her camera
and
have more space to shoot. After 5 days of hiking in somewhat dusty
conditions, the hard drive malfunctioned and most of her work was
lost.
I wonder if it was altitude (reduced atmospheric pressure) rather than
dust? I recall reading somewhere about people encountering altitude
limits on either hard drives or possibly even compact memory cards.
(I can't quite see why a card would be affected, though.)
Of course, dead is dead, regardless of the cause. But if it was air
pressure, "better dust filters" wouldn't make any difference. And,
gee, I thought that drives were sealed anyway. ?
Hard drives are sealed,but they definitely have operational altitude
limits (actually atmospheric pressure), typically rated around 10,000
feet, for this reason. I'd never trust an off the shelf hard drive in
extreme conditions like this (and very high or low altitudes are extreme
conditions). Besides, flash memory is extremely cheap these days, it's
getting harder to imagine trusting a cheap spinning disk when I can get
as much flash as I could need, and it's much more durable.
Just for instance, here is what Western Digital says for its drives:

I've personally had far few failures with digital photography than
film... but they fail in different ways. But frankly this anecdote is
just about someone using their equipment out of spec, and so constitutes
a "dumb user" moment. Film has its failure points too.
