Hi:

 

See if reinstalling the HP 3D Driveguard driver resolves the problem.

 

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.

 

File name: sp71811.exe

The "sp71811"  worked for me on an Envy 15T laptop running factory installed Win 10. Thanks for the info!
