HP 3D DriveGuard is HP software that protects the hard drive of HP notebooks and mobile workstations. It works with a three-axis digital accelerometer built into the notebook, which detects sudden motion such as a drop or an impact. HP 3D DriveGuard is a program that continually receives data from this sensor and temporarily parks the hard drive heads, so that damage is reduced if you drop the notebook accidentally or it smashes against something else.
Features:
It reduces the risk of hard drive damage and data loss when an HP notebook is dropped, bumped or hit by another object.
HP 3D DriveGuard helps protect notebook data from bumps and minor drops. It is useful only on HP notebooks with a traditional hard disk drive; desktops and SSDs, which have no moving parts, do not need it. HP distributes it free as a SoftPaq driver package for supported models. Older versions were called HP ProtectSmart Hard Drive Protection.
