You need this driver for that device...
This package provides the HP 3D DriveGuard Software for supported notebook models that are running a supported operating system. The 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.

You're very welcome.
I just know by studying drivers for hundreds of HP models, where to find them.
That driver came from the 640 G4's cousin, the EliteBook 850 G4.
I don't work for or represent HP, so I can't answer as to why HP doesn't list that driver on the 640 G4 support page.
