Tom Clancy's The Division

Drones are generally found stuck against the side of buildings that require you to climb them to reach it. Drones will only appear on your map if you are within a fairly close proximity to them and in most cases on the roof. When you get to a drone location, you will have to shoot the drone in order for it to drop its hard drive. Simply shoot the drone and collect the hard drive by holding to receive the collectible. The picture below is an example of a drone in-game:

In order to make collectibles appear on the map, you will have to activate the Security Wing of the Base of Operations and use the console to purchase the "Canine Unit" upgrade for 200 security supplies. Security supplies are earned by completing encounters and missions with the blue shield icon on your map. Once the Canine Unit is purchased, simply clear all side missions and encounters from a named zone to make Intel appear on the map. Note that some Intel items will not appear on the map due to their vicinity to other icons when zoomed out. In order to make them appear, push on your controller and push twice, to filter your map to only display Intel.

If you want view the drones you've collected, push the button on your controller, select Intel in your menu, push , and select Crashed Drones. The trophy will unlock when you collect the final drone.
