How long does this take? Only 2 – 5 minutes. It’s a good thing to do if you’re having any issues with your PS3. Say, for example, your blu-ray drive having issues, trophy syncing, performance issues, etc. If your PS3 ever shut off due to a power outage or shut off due to a buggy game. This would be a wise thing to do. Basically, what it’s doing is checking the PS3’s OS (operating system) for any corrupted files and restoring them if needed.

Let us know if this was helpful and what this may have fixed for you.

If you’re still having issues, I would try rebuilding the PS3 database.
I did a walkthrough on how to do that here. There are FAQ’s at the bottom of the post too.
