can't believe you've made a new post....
I had a look over your other post and you didn't follow or do as I'd suggested by reading the link for that particular game and just carried on posting....
Answer to no.5 a lot of people are not having this issue if they simply follow what is needed to be done for a specific game, GTA, Ghost, Ass Creed. they chop and change the disks so "content" is not always on Disk 1 etc. it's a simple process to follow.
