You need this driver...


This package provides HP 3D DriveGuard Software (HP ProtectSmart Hard Drive Protection) for supported notebook models that are running a supported operating system. HP 3D DriveGuard Software protects the hard drive by parking the heads if the notebook is accidentally dropped, or is abruptly impacted by another object.
