Bogota, Colombia has an elevation of 2,640m. A cable car in the city (Teleférico de Monserrate) can also take one to an elevation of 3,152m. Given that regular hard drives were usually pressurized to operate in elevations up to 3,000m, was there a high rate of hard drive failures in places like Bogota? Perhaps countries like Colombia had specially manufactured hard drives to deal with the issue?
Most modern hard disk drives are not pressurised. They have a "breather" hole (normally with an air filter) to let the internal and external air pressures equalise. They're normally rated to work at 3,000 metres altitude.
There's another requirement that's likely more commercially significant than working in Bogota, which is working in a pressurised airliner. Those have a regulatory requirement to keep the pressure equivalent to 2,400 metres or less, so Bogota at 2,640m is a slightly stricter requirement.
If hard drives are rated to work at 3,000m, they likely have at least a 10% safety margin, so Bogota on a low-pressure day should not be a problem. There are genuinely sealed drives produced, for working at higher altitudes, but they're bound to be much more expensive, given the limited need for them. It looks as if ordinary ones should be fine in Colombia.
Some modern hard drives are sealed and filled with helium. These were developed by Hitachi Global Storage Technologies, now part of Western Digital. Using helium reduces turbulence and friction, allowing narrower recording tracks and thus higher density, although the difference is not huge. Helium-filled drives have to be very thoroughly sealed, since helium is good at escaping, and should be fine at high altitudes.
TL;DR: Rather not.
Given that regular hard drives were usually pressurized
Fixed (!) drives are not pressurized. If they were, there would be no issue. They are usually sealed to avoid any dust intake (*1), but the seals are flexible to allow expansion.
to operate in elevations up to 3,000m,
Since many manufacturer were often US companies the value is often given as 10,000 ft (3,048m). But this is not really a measurement of height, but pressure. Standard pressure for 3,048 m is 697 hPa (*2).
More important, it is not a hard technical limit in any way, but an environmental spec to which the manufacturer guarantees that the drive will always work. It does not give any hint what happens outside that limit.
Even if there is some concern, the margin of error will be at least 20%, so if 697 hPa is guaranteed, then it's safe to assume that nothing will happen up to 20% lower - that is 540 hPa, or a standard height of ca. 4,770 m.
The specific value has most likely been selected to allow regular use in (pressurized) passenger aircraft, which are set per regulation at or below 8,000 ft above sea level.
was there a high rate of hard drive failures in places like Bogota?
No. Never heard of.
- For one, as explained, 10,000 ft are neither a hard limit or a limit at all, but a guaranteed operational condition.
- Second, the seal may at most simply pop, which equalizes pressure - but I'm not sure that coming easy
- Third, even if, there are still filters keeping dust out
On a side note:
- Real pressure depends not only on height, but location, weather and time of day. For example today's real pressure at in Bogota at 11 PM at 2,618 m altitude is 757 hPa, which is more like 2,400 (2,600m would be 737 hPa)
*1 - Modern drives as well to keep whatever gas is used to fill (like Helium) inside.
La Paz, Bolivia is higher than Bogota Colombia. In the mid 1970s I was an instructor for Digital Equipment Corporation, and I taught some courses to a customer in La Paz. The customer had bought a large timesharing system with several disk drives.
Those disk drives had been tested at a low pressure chamber in Colorado before being certified as ok to work in La Paz. It's air pressure generated by the Bernoulli effect that keeps the heads from crashing into the recording surface. In effect, this gives them a maximum flying altitude.
