I understand what you are saying, but maybe you misunderstood what I typed! The bddrive only has one lens, but there are several software demands that read differently. The higher speed is what I think was changed. The dvd rom, and playstation 2 games are slower speeds, they don't push the drive. The issue is the drive functions but when you put in a Blueraye game it will read, but when it freezes either you hard cut it off from the back, or you press the eject button and quit the game after the disc has been ejected, but whatever you do following either of those processes your drive will not read the blueraye disc thats in the drive or when you insert it back in.
You will have to power of the system and then it will read your blueraye disc untill it freezes again. But your Dvd's and playstation 2 games will always read. And all drives that have the same interlink can work in any playstation. I was not going to send you guys my playstation. I love my half messed up machine, lol. Mad at Sony, but The problem will get worked out because its something that can be tested to see the mistakes, all sony has to do is find a code that works for all models.
I hope this cleared up my last post, and I put my drive in a cech because they have the same data link as mine, his was bought in 08
