If you have the game installed on a hard drive but the Battle.net app doesn't see it (and tries to make you download 30GB again), you need to "link" the existing data.

The Digital Limbo: Navigating StarCraft II’s "Preparing Game Data" Loop For veterans of the Koprulu Sector, the launch of StarCraft II
is typically a ritual of swift menus and the immediate thrum of a Terran orbital command or a Zerg hive. However, a persistent technical anomaly—the "Preparing Game Data" link—has transformed this ritual into a test of patience for many players. This phenomenon represents more than just a minor bug; it is a clash between aging game architecture, modern operating systems, and localization management. The Anatomy of the Error
The "Preparing Game Data" prompt is essentially a background update mechanism that triggers when the game client detects a discrepancy between the local files and the server’s expected data state. While it is a standard procedure after a major patch, the "bug" occurs when this window appears every single time the game is launched, often forcing a download of several hundred megabytes at agonizingly slow speeds.
This digital purgatory is frequently rooted in localization mismatches. Players who change their text or audio language settings—shifting from English to Spanish or Russian, for instance—often find the client unable to permanently "link" these new assets. Every restart, the game attempts to re-verify or re-download these packs, a process exacerbated by Blizzard's legacy servers, which sometimes cap these specific background downloads at speeds reminiscent of the dial-up era. The Technical Friction
Beyond language packs, the issue often stems from conflicts with modern system features like OneDrive. Many technical support threads on the StarCraft II Forums suggest that OneDrive’s cloud synchronization can "lock" or move game configuration files, preventing the Battle.net launcher from correctly identifying that the "game data link" has already been established. Community-Driven Solutions
Because a definitive developer-side patch has remained elusive, the community has engineered several workarounds to bypass this loop: Preparing game data - Technical Support - SC2 Forums
Troubleshooting StarCraft 2: Fix the "Preparing Game Data" Loop starcraft 2 preparing game data link
The "Preparing Game Data" screen in StarCraft II is a notorious bottleneck that often appears after a patch or when changing language settings. While it is technically a normal part of the game's file verification and update process, many players experience a bug where it downloads at abysmally slow speeds (often 5–300 KB/s) or appears every single time the game is launched. Why This Happens
Language Mismatches: The game client may be set to a different language than the Battle.net launcher, forcing a slow download of high-quality audio files.
Corrupted Cache: Old files in the Battle.net or Blizzard app data folders can cause the "preparing" step to hang.
Permission Issues: The game may be waiting for Windows Administrator approval to install specific updates in the background. Step 1: Synchronize Language Settings
The most common "instant fix" for this loop involves ensuring your game and launcher languages match. Open the Battle.net Desktop App.
Click on StarCraft II and select the Gear (Options) icon next to the Play button. Choose Game Settings.
Ensure both Text Language and Spoken Language are set to the same thing (e.g., English).
If you use a non-English language, try switching both to English first to see if the download completes, then switch back to your native language. Step 2: Use the SC2 Switcher to Bypass the Launcher
If the Battle.net launcher is stuck, you can bypass it entirely by launching the game executable directly.
Navigate to your StarCraft II installation folder (usually C:\Program Files (x86)\StarCraft II). Open the Support64 folder. Double-click SC2Switcher_x64.exe.
You may need to log in manually within the game, but this often avoids the "Preparing Game Data" loop. Step 3: Clear the Blizzard Cache Folders
Corrupted temporary files are a frequent culprit for stuck downloads. Press Windows Key + R, type %APPDATA%, and press Enter. Delete the Bnet and Blizzard folders.
Repeat this process by typing %LOCALAPPDATA% and %TEMP% into the Run window and deleting the same folders there. Empty your Recycle Bin and restart the Battle.net app. Step 4: Run as Administrator and Scan/Repair
If the game lacks the permissions to write new data to your drive, it will hang indefinitely. Preparing game data - Technical Support - SC2 Forums
Report: Preparing Game Data Link for StarCraft 2
Introduction
StarCraft 2 is a popular real-time strategy game developed by Blizzard Entertainment. The game requires a significant amount of data to be loaded into memory before gameplay can begin. This report focuses on the process of preparing the game data link for StarCraft 2, which is a critical step in ensuring a smooth gaming experience.
Background
When a player launches StarCraft 2, the game client needs to load a vast amount of data into memory, including game assets, maps, and metadata. This data is stored on disk and must be transferred into memory before the game can start. The process of preparing the game data link is responsible for loading this data into memory.
The Data Link Preparation Process
The data link preparation process in StarCraft 2 involves the following steps:
Challenges and Optimizations
Preparing the game data link for StarCraft 2 poses several challenges:
To optimize the data link preparation process, Blizzard Entertainment has implemented several techniques:
Conclusion
Preparing the game data link for StarCraft 2 is a critical step in ensuring a smooth gaming experience. The process involves data indexing, loading, decompression, and verification. While there are challenges associated with large data sizes, data compression, and disk I/O, Blizzard Entertainment has implemented several optimizations, including caching, multi-threading, and data compression. These optimizations have helped to reduce loading times and improve overall gameplay performance.
Recommendations
Future Work
Here is the proper text version, depending on the exact meaning:
Most likely (menu button or status message):
StarCraft II: Preparing game data...
(then separately, a link or button for "Link" or "Battle.net link")
If it's a single phrase (e.g., a tooltip or instruction):
StarCraft II: Preparing game data link
If it's a sentence explaining the link's purpose:
StarCraft II is preparing the game data link.
Key corrections made:
If the automatic method fails, force the app to look for the game.
If you need raw game data to train a model, you need .SC2Replay files.
