Yeah, the lense issue is rather problematic with the PS3 FAT models.
But it should have been better if this will make SONY reconsider about making game that will run from HDD instead. And use minimal lense to seek as much as possible after the installation. For example, loading it with serial code like PS2, each game can have serial number code scrambled in the start of the section. And each installed game have to have a unique code. But this will come down to problem when people lending your games lol.

Oh well. scrambled this and redraw the scenarios.
