Hello @Ash52,

Thank you for the quick reply!

There is a driver you can download, that should resolve the issue for you.

Try checking this site.  Once there, input your Product Number and click "Go". You can select your product on the next screen, using the drop down "+", on the right. On your product support page, you can select Software and Drivers, then click the "Go", that is under Option 2. Once you select your Operating System and click "Update", you should be able to access and download the driver. The category that you are looking for is Software-Solutions.  The name of the driver will either be HP ProtectSmart Hard Drive Protection or HP 3D DriveGuard Software (HP ProtectSmart Hard Drive Protection), depending on your product.

I hope this helps.

Regards!
