PlayStation PS5 CE-100028-1 Error
What it means
CE-100028-1 means there is not enough free space on the PS5's storage to complete what you are doing — installing a game, downloading an update, or saving a capture. The console blocks the operation until you free up space.
Common causes of the CE-100028-1 error
- The internal SSD is genuinely close to full
- Many large games installed at once leaving little headroom
- A large game update or download that needs more space than is available
- A corrupted storage database reporting incorrect free space even when the drive has room
- Old saved data and captures accumulating over time
How to fix the PlayStation PS5 CE-100028-1 error
- 1Check how much free space you haveGo to Settings → Storage → Console Storage → Games and Apps. If the 'Free' figure is very low (under about 30 GB), the error is legitimate and you simply need to free up space.
- 2Delete games you are not playingIn Games and Apps, sort the list by size, highlight a game you have not played recently, press the Options button, and choose Delete. Your saves, licenses, and trophies stay safe on PlayStation Network, and you can redownload the game later for free.
- 3Clear old saved data and capturesUnder Settings → Storage → Console Storage, remove old saved data for games you no longer play (most are backed up to PS Plus cloud) and delete large screenshots and video clips you do not need.
- 4Rebuild the database in Safe ModeIf you appear to have plenty of free space but still get the error, rebuild the database. Fully power off the PS5 (hold Power until the fans stop), then hold Power again and release after the second beep to enter Safe Mode. Choose option 'Rebuild Database'. This does not delete your games or saves.
- 5Add or use external/expanded storageMove PS4 games and stored PS5 games to a USB 3.0 external drive to free the internal SSD, or install an M.2 SSD expansion card for permanent extra space for PS5 games.
🧰 When to call a professional
This error almost never needs professional repair. Only contact PlayStation Support if you have freed up substantial space and rebuilt the database but the console still reports the drive as full, which could indicate a failing SSD.
PlayStation CE-100028-1 error — FAQ
Will deleting a game to fix CE-100028-1 lose my progress?
No. Deleting a game removes only the install files. Your save data, trophies, and license stay on your account, and you can redownload the game at no cost whenever you want.
I have lots of free space but still get CE-100028-1. Why?
The storage database can fall out of sync and report the wrong free space. Boot into Safe Mode and run Rebuild Database — it recalculates space without deleting your games or saves.
How much free space should I keep on the PS5?
Leave at least about 50 GB free on the internal SSD. The console uses that headroom for installs, patches, and system cache, which helps prevent this error from recurring.
