AccelerometerSt.exe runs the system tray process for the 3D DriveGuard. This is not an essential Windows process and can be disabled if known to create problems. HP 3D DriveGuard is a safety device for hard drives that protects them against accidents, and major wear and tear through rough use. The device is named after the three-axis digital accelerometer that acts as a motion sensor, alerting the system of any sharp movements and automatically parking the hard drive to prevent any damage to data. HP 3D DriveGuard supports the Microsoft Windows platform. Hewlett-Packard was founded by Bill Hewlett and Dave Packard, two Stanford graduates in electrical engineering, in 1939. It started out in Packard's Garage in Palo Alto, California. For the major part of the 20th century, the company focused on a wide range of electronic products but slowly grew out into producing computing-specific hardware from the 1970s onwards. Today, it provides hardware, software and services to consumers and various types of businesses and large corporations. Hewlett-Packard is headquartered in Palo Alto, California, USA.
