What is a PS4/PS5 database rebuild?
A Database Rebuild on PS4 and PS5 means that the Safe Mode troubleshooter will scan the entire internal storage. In particular, it’ll look for errors like broken, corrupted, and duplicated files. It’ll then create a new database by cleaning and restoring all the data. Moreover, it recognizes the drive so that the PlayStation can access game files and system files faster. For instance, it’ll put the related items together instead of scattered all over the drive for inefficient performance. This won’t work on external storage. Instead, it’s advised that you should manage your drives before the process. For instance, uninstalling the games and deleting the data that you aren’t using from your drive. Then, you can copy the data and titles that you’re using from the external storage to the internal drive. Lastly, a PS4 or PS5 rebuild could take hours but it’ll ultimately depend on the state of your console. The number of games you have and how often you install/delete games also influence the length of the process.
