Data driven

As you explore the map you'll come across FICSIT crash sites with pieces of wreckage scattered about. There's usually some decent enough loot here - but one of the larger pieces of wreckage will have a safe containing a hard drive. Open the safe and take it. Some can just be opened on the spot - but some others require power delivery (e.g. 60MW) or some components/materials/items to unlock, so its worth bringing a variety of crafting materials with you when exploring - and perhaps even stringing out power lines along the way.

Note, per the achievement's description, you have to find the hard drives in crash sites. Buying from the Awesome Shop doesn't count.
