Security Option "Audit: Force audit policy subcategory settings (Windows Vista or later) to override audit policy category settings" must be set to "Enabled" (WN10-SO-000030) for the detailed auditing subcategories to be effective.

Use the AuditPol tool to review the current Audit Policy configuration:
Open a Command Prompt with elevated privileges ("Run as Administrator").
Enter "AuditPol /get /category:*"

Compare the AuditPol settings with the following. If the system does not audit the following, this is a finding:

Object Access >> Removable Storage - Failure

Some virtual machines may generate excessive audit events for access to the virtual hard disk itself when this setting is enabled. This may be set to Not Configured in such cases and would not be a finding. This must be documented with the ISSO to include mitigations such as monitoring or restricting any actual removable storage connected to the VM.
