Crash Site

Wreckages can be found all across the World. Scattered around the wreckage are various components such as wires, reinforced iron plates, and computers. There will also be a Drop pod that (usually) needs to be repaired in order to access the Hard Drive inside it. Wreckages are generally either located in hard-to-access areas, or are guarded by large creatures. Some wreckages may be located inside poison gas.

Locating
Once the Object Scanner is obtained and equipped at Tier 0: Hub Upgrade 5, you can right-click it and set it to Crash Sites to search for drop pods. The object scanner will point to the nearest drop pod regardless if the Hard Drive inside it has been retrieved.

Additionally, there are several fan-made maps listing wreckage locations.

Retrieving The Hard Drive
First the drop-pod needs to be repaired. Open the drop-pod's UI to find out what specific items need to be present in the Engineer's Inventory. Alternatively, the drop-pod may require Power to be repaired. If this is the case, build temporary Biomass Burners or Coal Generators to supply it with temporary power, or connect it to a power grid. The supplied power must not be less than the required power else there will be a power trip.

When the requirements are fulfilled, the handle on the drop-pod UI can be dragged down, opening a hatch and allowing the Engineer to retrieve the Hard Drive.
