Example

This is an evented table, and as such, is more useful if you are sending osquery logs to a SIEM or other centralized destination via Fleet. Events must be enabled. This query will contain the list of all actions related to connecting and removing disks, including SMB drives and USB storage, which can be very useful for investigative purposes.

SELECT * FROM disk_events;
