Wasn't that Tenzing Norgay, a Sherpa?
Not well thought out.
The hard drive in the computer has heads that "fly" just a few millionths of an inch off the disk on a cushion of air. If air density is reduced (as it is at altitude), the head will fly lower, vastly increasing the risk of a head crash and consequent destruction of the drive and all data. Because of this, I know of no commercially available hard drives that are rated to perform at over 10,000 feet in altitude. At 17,400 feet spoken of in this article, density is approximately 50% of that found at sea level.
