How to Fix PS5 Error CE-100028-1: Not Enough Free Space on SSD (2026)

If your PS5 throws error code CE-100028-1 every time you try to install a game, download a patch, or update the system software, the console is telling you there is not enough free space on its internal SSD. This is the single most common storage error on the PS5, and in most cases it is exactly what it says — the drive is full, or the installer needs more working room than the space you have left. Below are the fixes that actually clear the error in 2026, in the order you should try them.

Why You See PS5 Error CE-100028-1

The PS5’s 825 GB and 1 TB models only give you around 667 GB and 842 GB of usable space after the operating system takes its share. The PS5 Slim 1 TB ships with roughly 842 GB free on a fresh setup. Most modern AAA games install at 80 – 150 GB, and system updates need working space of at least the size of the game being patched. Call of Duty and Modern Warfare installs alone routinely push past 230 GB with all mode packs, so it does not take many titles before CE-100028-1 starts appearing.

There are three realistic root causes:

You genuinely have less than the required free space. Even if the dashboard shows 10 – 15 GB remaining, the installer needs extra temporary space to unpack a download, so a patch that is “only 8 GB” can fail with CE-100028-1.
The PS5 database is corrupted. If the file index is out of sync with what is actually on the SSD, the console can miscalculate free space and block installs even when space is available.
Capture Gallery, messages, and save data have grown unnoticed. Screenshots and recorded clips are saved to the console storage by default and can take tens of gigabytes after a year of gaming.

Fix 1: Check Your Actual Free Space

Before anything else, confirm how much space you really have. On the PS5 home screen, go to Settings → Storage → Console Storage. You will see total capacity, free space, and a breakdown by Games and Apps, Media Gallery, Saved Data, and Other.

If the “Free” column is under 30 GB, the error is almost certainly legitimate and you need to free up space before any other fix will stick. If you have more than 30 GB free and are still hitting CE-100028-1 on a small patch, skip ahead to Fix 4 (Rebuild Database).

Fix 2: Delete Games, Patches, and DLC You Are Not Playing

This is the fastest fix if your SSD is full. On the PS5, open Settings → Storage → Console Storage → Games and Apps. The list can be sorted by size — use that, not alphabetical, so you see which titles are actually eating your drive.

Select any game you have not launched in the past month, press the Options button on the controller, and choose Delete. Your save data, licenses, and trophies stay intact on PlayStation Network; only the install files are removed. You can redownload the title later at no cost.

For games you want to keep installed but trim down, select the game and check Game Presets. Many live-service games let you uninstall campaign or multiplayer components independently — Call of Duty, for example, lets you remove the Campaign pack and keep Warzone, saving 40 – 60 GB.

Fix 3: Clear the Capture Gallery and Old Saved Data

The Capture Gallery is often the hidden culprit. The PS5 records the last 15 minutes of gameplay in the background, and screenshots also default to console storage. Go to the Media Gallery app (on the home screen function row), press Options on any clip or screenshot, and choose Delete. You can multi-select to wipe the gallery in bulk.

To change this going forward so captures do not pile up again, open Settings → Captures and Broadcasts → Captures → Save Location and point it to an external USB drive, or lower the video clip length from 60 minutes back to 15.

While you are there, also clear old saved data for games you no longer play under Settings → Storage → Console Storage → Saved Data. Most games have PlayStation Plus cloud backups, so local saves can be removed safely if you have PS Plus.

Fix 4: Rebuild the PS5 Database in Safe Mode

If you have plenty of free space on paper but still get CE-100028-1, the database is almost certainly out of sync. Rebuilding it fixes the free-space calculation without deleting any of your games, saves, trophies, or accounts.

Boot into Safe Mode:

Fully power down the PS5 (hold the Power button until the fans stop — not Rest Mode).
Press and hold the Power button again. Release it after the second beep, roughly seven seconds in. The console boots into Safe Mode.
Connect the DualSense controller with the included USB-C cable and press the PS button.
Select Option 5: Rebuild Database.

The rebuild can take anywhere from 10 minutes to several hours depending on how full the drive is. Do not unplug the console during the process. When it finishes, the PS5 reboots normally and free-space reporting is corrected. Try the install or update again.

Fix 5: Clear the PS5’s Update File Cache

Failed downloads sometimes leave partial update files stranded on the drive, taking up several gigabytes without showing in the storage breakdown. Boot into Safe Mode again using the steps above and select Option 3: Update System Software → Update from USB Storage. Back out without updating — the menu refresh flushes the incomplete download cache. This is a community-sourced fix that resolves CE-100028-1 cases where rebuilding the database alone did not work.

After the reboot, cancel any currently queued downloads under Settings → Downloads/Uploads, then restart the download from scratch.

Fix 6: Move or Install Games to External USB Storage

A USB 3.0 external drive is the cheapest way to buy yourself breathing room. You cannot play PS5 games directly from external USB storage, but you can store PS5 games on it and play PS4 games directly. Moving your library frees the internal SSD for active PS5 titles.

You need a USB 3.0 or faster drive, at least 250 GB and no larger than 8 TB. Plug it into one of the rear USB-A ports (the front port works but is slower on older PS5 models). Then go to Settings → Storage → USB Extended Storage → Format as USB Extended Storage. Formatting erases everything on the drive.

Solid recommendations:

Seagate Game Drive for PlayStation 2 TB (HDD, USB 3.2 Gen 1) — officially licensed, plug-and-play, the best value for archiving games you rotate in and out.
Seagate Game Drive for PS5 External SSD 2 TB — SSD version with faster PS4 play and faster file transfers; worth it if you move titles back and forth often.

Spot-check the Amazon listings before buying — stock and pricing on external storage swings weekly.

Fix 7: Install an M.2 SSD (the Permanent Fix)

If you hit CE-100028-1 every couple of weeks, the right long-term fix is to add an internal M.2 SSD. Unlike USB storage, games installed on an M.2 SSD run natively at full PS5 speeds, and the console sees it as a normal second drive.

Requirements Sony enforces:

PCIe Gen 4 × 4 NVMe M.2 SSD
M.2 form factor 2230, 2242, 2260, 2280, or 22110
Sequential read speed of 5,500 MB/s or faster (Sony’s minimum)
An effective heatsink — most failures are thermal, not electrical

Drives that meet every requirement and are widely confirmed to work:

WD_BLACK SN850X 2 TB with Heatsink — 7,300 MB/s read, purpose-built for PS5, the most widely recommended pick.
Samsung 990 PRO 2 TB with Heatsink — 7,450 MB/s read, Samsung’s fastest PS5-compatible drive.
Samsung 990 PRO 4 TB with Heatsink — step up to 4 TB if you play many large open-world games.

Installation is straightforward and does not void the warranty as of the PS5 firmware released in 2022 and later. Unplug the console, remove the top cover, unscrew the M.2 expansion slot cover, install the drive, re-seat the spacer for your drive’s length, then power on — the PS5 will prompt you to format it automatically. Once complete, you can move games between the internal SSD and the M.2 expansion from Settings → Storage.

Fix 8: Factory Reset (Last Resort)

If CE-100028-1 persists even after a rebuild and you have plenty of free space, the console software itself may be corrupted. A factory reset reinstalls the system and clears every stored file. Back up your saves to PS Plus cloud or a USB drive first — factory reset wipes them.

Back into Safe Mode, choose Option 7: Reset PS5 (Reinstall System Software). This option requires a USB-formatted FAT32 or exFAT drive with the latest PS5 system software downloaded from Sony’s support site and placed in the path PS5/UPDATE/PS5UPDATE.PUP. Follow the on-screen prompts. The console is back to factory condition after about 15 minutes.

When To Contact Sony

If none of the steps above work, the SSD itself may be failing — modern NVMe drives do wear out, especially the TLC NAND inside the launch PS5 model. Symptoms include CE-100028-1 appearing alongside random freezes, slow load times, or CE-108255-1 and CE-100005-6 read errors.

Contact PlayStation Support at 1-800-345-7669 in the US. Consoles are covered by Sony’s 12-month warranty from date of purchase, and extended PlayStation Protection Plans cover hardware failures after that. Proof of purchase is required. Sony will usually direct you to playstation.com/support/hardware/ps5-console to start a repair or replacement RMA.

Preventing CE-100028-1 From Coming Back

Once the error is fixed, two habits will keep it from returning:

Leave at least 50 GB free on the internal SSD at all times. The PS5 uses this headroom for installs, patches, and system cache.
Send captures to an external drive by default. Set this once under Settings → Captures and Broadcasts, and the Media Gallery will stop silently eating your storage.

If you play 4 – 6 large games actively and keep a handful of old favorites installed, the only permanent answer is adding an M.2 SSD. Two terabytes of expansion storage costs less than a single AAA release and eliminates CE-100028-1 for the life of the console.
