Class name	Desc_HardDrive_C
Item
Stack size	100

Hard Drives are special items obtained from Crash Sites used to unlock alternate recipes (see below). Crash Sites can be located using Object Scanner after Radio Signal Scanning has been researched in the MAM.

Each Hard Drive can be researched in the MAM and results in a choice of one of two alternate blueprints, chosen from the pool below, as well as two pioneer inventory expansions.

There are 118 Crash Sites, which means a total of 118 Hard Drives can be obtained. Four Hard Drives can be used to unlock alternate recipes via MAM research trees (as opposed to scanning the drives). Scanning the drives will provide a total of 108 recipes plus two opportunities for pioneer inventory expansions, using only 107 Hard Drives for recipes due to Quartz Purification also unlocking Distilled Silica for a single scan. This leaves 5 Hard Drives unused.

Alternate recipes

Choices for alternate recipes granted by analyzing a Hard Drive

There are a total of 113 alternate recipes available. 108 are acquired via Hard Drive scanning, four (Compacted Coal, Turbofuel, Rocket Fuel and Ionized Fuel) are unlocked via MAM research trees. One alternate recipe, Polyester Fabric, does not cost a Hard Drive to unlock. Distilled Silica is unlocked together with Quartz Purification, sharing a single Hard Drive requirement.

Alternate recipes use different input materials than the original, balancing factors such as raw material consumption, space, power, simplicity, and material availability. Alternate recipes cannot be considered upgrades.

Two alternate recipes are chosen at the beginning of the scan and revealed to the player after the 10 minute research concludes. If the player chooses not to select an alternate recipe, they can access the selection menu at a later time via the hard drive library. The selected alternate recipe is unlocked for use immediately. Alternate recipes can be only used in factory buildings, not in the Craft Bench. Therefore, parts like Compacted Coal cannot be hand-crafted.

For an alternate recipe to appear in the selection, certain prerequisites (Milestone, MAM Research, or another alternate recipe) have to be met. If there aren't at least 2 available alternate recipes available from the current prerequisites, MAM will refuse to scan it and print "no rewards currently available". Unlocking more prerequisites during an ongoing scan won't affect the choices presented at the end of the scan, as these choices are determined at the beginning of the scan.

Note: Typically a recipe will become available to unlock as soon as the player has access to every material within it, but not necessary the building required to actually use it. This means that, for example, the "Pure" alts that require a Refinery become available as soon as the Water Extractor can be built, while the Alloy Ingot recipes, needing only ore, are available immediately despite requiring a Foundry.

In the table below, the prerequisites are the conditions that are required for a recipe to be able to appear in the research result choices. If no prerequisite is displayed, the recipe is available immediately in the recipe pool (but you still need MAM to scan the Hard Drive). Note that some alternate recipes may require player to unlock a new building so that they could be automated.

Hard Drive Library

This article is a stub. You can help Satisfactory Wiki by expanding it.

Scanning a Hard Drive in the MAM stores it in the Hard Drive library. The library allows storing scanned Hard Drives without immediately choosing a reward, allowing players to delay their choices and potentially choose their rewards more strategically.

Storing multiple Hard Drives in the library narrows down the pool of rewards for newly scanned and re-rolled drives, as rewards will not repeat. This increases the likelihood of obtaining a desired reward, as the pool is reduced by two options, instead of just one (the selected reward).

It is possible to re-roll the presented rewards for each Hard Drive once. This means being able to choose from four unique rewards from a single Hard Drive. Re-rolling is also limited by other Hard Drives in the library, just like scanning a Hard Drive anew.

Usage

AWESOME Sink

 Hard Drive cannot be sunk into the AWESOME Sink and will clog the input.

Research

 Hard Drive is used for research in the Sulfur Research chain in the MAM.

Non-recipes from Hard Drives

Besides Alternate Recipes, two inventory expansions can be unlocked:

Name	Effect	Prerequisites
Inflated Pocket Dimension	+6 Inventory Slots	none - see below
Inflated Pocket Dimension	+6 Inventory Slots	Tier 6 - Industrial Manufacturing

There are no explicit prerequisites for the first inventory expansion - you only need to have the MAM unlocked from Tier 1. After the launch of 1.0 the first inventory expansion can be obtained with only a single hard drive.

Important notes

• The Hard Drive research is repeatable, as long as there are remaining alternate recipes to unlock.
  • Each alternate recipe can only be unlocked once, it will never appear in the selection screen again once it has been selected.
• The game does not list which alternate recipes are unlocked in one place, the Codex has to be searched for them.

Tips

• Research within the MAM continues regardless of a MAM being present on the map, also multiple MAMs may be constructed. Therefore, when a Hard Drive has been acquired, the player may build a MAM at the crash site, load the Hard Drive in, and then remove the MAM, continuing their search for further drives without building a backlog of Hard Drives to research (or, if they acquire drives faster than a rate of one per 10 minutes, can significantly reduce the amount of drives in their backlog). Only one Hard Drive can be researched at a time, meaning multiple MAMs cannot be used to research more than one Hard Drive at a time.
