HP Support were useless. I worked out a simple fix to remove hpdskflt associated with every drive as noted below. I left the HP Mobile Protection Sensor in Device Manger alone since it just reinstalls if you uninstall it. There should be an option to disable the device but HP do not allow this option. I also didn't fiddle with the other settings for hpdskflt.sys since the driver is associated with the HP Mobile Protection Sensor which cannot be uninstalled.

How to remove hpdskflt associated with all drives.
Delete the lower filter for hpdskflt at
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}
Reboot.

PS - do backup before you try this
