Symptoms
- Save file won't load or shows an error
- Progress reverted to an earlier point unexpectedly
- Save file missing entirely from the list
- Game crashes specifically when loading a save
Likely causes
- CommonPower loss or forced shutdown during a saveInterrupting the write process can corrupt the file.
- CommonStorage drive developing errorsBad sectors on a drive can corrupt files stored there.
- PossibleGame software bug affecting save filesSome games have known bugs that corrupt saves under certain conditions.
- PossibleInterrupted cloud syncA save can be partially uploaded or downloaded if connection drops.
- Less commonFailing storage drivePhysical drive failure can corrupt or lose multiple save files.
What to do
- Check if cloud save backup is enabled and try restoring from the most recent cloud save.
- Avoid turning off the console manually while a save or sync is in progress going forward.
- Try loading the save again after a full console restart in case it was a temporary read error.
- Check the game for an autosave or backup save slot as an alternative.
- Verify the storage drive isn't showing other signs of failure, like slow performance or read errors elsewhere.
- Enable automatic cloud saving if it wasn't already on, to protect future progress.
- If saves corrupt repeatedly across multiple games, have the storage drive checked or replaced.
When to call a pro
If corruption happens repeatedly across different games, a repair shop can test whether the storage drive itself is failing.
