Solving error CE-100005-6 on PlayStation 5
Error code CE-100005-6 on the PlayStation 5 is officially considered a disc-reading problem. The text of the message says so, but there is a failure in completely different situations. An error can be displayed when trying to install or run a digital copy of the game, as well as when updating the operating system, applications. All of this hints that the disk read error is not directly related to the disk.
What to do?
We managed to find out that the error CE-100005-6 appears due to a lack of free space on the SSD. We came to a similar conclusion as a result of a study of user reports. The thing is that for the console to work correctly, it needs more than 100 GB of free space. If you have 100 GB of space and try to update or install a new game, even within the specified amount, this error appears. All you have to do is uninstall apps, games, and files to free up more space. Once you have 100 GB+ of the game you want to install, the system will work properly.
Another option is to buy an additional SSD and move some of the games to it. This approach will also increase the amount of free space, but will not require you to remove installed games. The choice is yours.
