| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. In computer
hardware, active hard drive protection refers to technology that
attempts to avoid or reduce mechanical damage to hard disk drives by
preparing the disk(s) prior to impact. This approach is mainly used in
laptop computers that are frequently carried around and more prone to
impacts than desktop computers. Usually the system consists of
accelerometers that alert the system when excess acceleration or
vibration is detected. The software then tells the hard disk to unload
its heads to prevent them coming in contact with the platter, thus
potentially preventing head crash. This technology only engages if the
hard drive is running at the moment of impact. Modern hard drives are
designed to unload their heads when they lose power. |
