To give you the complete picture (for future reference ?), this is what made me perform all this.
My PS3 fat (500 gig) started acting weird last week.
- I got kicked offline several times while in seasonals. Each time I wanted to restart a TT, the screen went black, while the background music kept playing. No times were recorded.
- In the home menu, the little timer (which usually works a few seconds) always kept turning for about 50" on each and every action in did.
Also, when I shut the system down I got 3 short beeps ! Never had that happen before.
-----------------------------------------------------------
I started looking around the Internet (I don't know a lot of computers) and found some possible problems: hard disc failure, disc drive failure, system overheating ...
Checked the last part, but since the PS3 has enough cooling space behind it and is standing on an aluminium plate (and the outgoing air was barely warm), that could hardly be the issue.
Having read what to do, I started with synchronizing the trophies online (if you don't, you lose them all - says Sony)
Then I was going to make a full backup on a external 320 GB hard drive (formatted to fat32 - since that is needed to be recognized by PS).
After some 15' I got the message that there was not enough disc space available !?
Reading again on the internet, I learned that it was better to format the external hard drive on PS3 itself.
Did that, but after a few moments I realized that I must have hit a wrong button, since the system was formatting the internal drive...
Well, no harm done, I just had to re-install the whole game (I had my game savings on a flash drive).
That was really time consuming, but after some 7 hours, I restarted the PS3, got a different background in the XMB menu, fired up GT6 and started with a track day on Brands Hatch (with a lot of explanation how to play the game)
So, now it was time to use the backup of the game data. That done I got all my credits and cars back, also the full statistics.
The only thing that was missing were the car icons in garage and stockyard. I had to restore them too, and that also took a long time.
But in the end the little timer was still counting for about 50" in the home menu...
Then I found the manual I linked in my post #7 (above this). Did that and everything works fine now (after re-adjusting some of the custom settings).
So, probably this should have been my first action. Would have saved me a lot of time.
Hope this helps people who suffer the same problems...
