Microdrives don't work well, and may even fail to work, at high altitudes, above 9,000 feet.
>From IBM: "The Microdrive does need "AIR" to float the heads and typically above 10,000 ft the mass of the air is too low and the drive requires a pressurized environment similar to an aircraft or spacecraft. At high altitude the air bearings begin to loose support from the air molecules needed to provide the "air bearing" for the Negative Air Bearing Surface (NABS) design of the head. If this "air bearing" is removed or lowered (as is the case with low density air at high altitudes) the head damages the media and you could have loss of data. The drive is vented to maintain equal pressure inside and outside to provide the air and to maintain the same pressure. This eliminates the need for sealed and rigid covers that can tolerate pressure differences. The OEM Functional specification defines the warranty range for operating altitude as 3,000 M or 9,000 ft (3ft/M) ...."
