Most hard drives these days have internal temperature sensors and many failing drives are simply shutting themselves down due to an "over temperature" trip point being reached. Some HDD diagnostic software will read the temperature sensor.
A lot of laptop hard drives (and desk top hard drives) are installed upside down. They tend wear out bearing surfaces that are intended to be loaded in a different plane than the one the laptop/computer manufacturer has used (often purely for packing reasons). The worn bearing surface means the motor needs extra power to keep the platters spinning at the correct speed, and this tends to cook the drive.
After the first couple of days of hot weather, there's usually an avalanche of failed or failing hard drives due to the over temperature alarm tripping.
