Thanks but I need to know what to do after I take apart the ps3 and BR drive. Do I manually remove the disc after it stops spinning? (like I don't press anything for it to come out but just take the disc out)
After that, do I just insert the back up and play? Is that all? Also, by manually removing the disc while having an open ps3 on, is there a chance that the electricity will hit me?
Ya, I am only answering the part of your question quoted above... where to find Tutorials/Videos on how to take apart the PS3. You'll have to read the rest of the thread and wait for others to reply for answers to your remaining questions... or just do what most people do- experiment on your own a bit.
The magnet is under the white plastic disc.. just like it's been for 7+ years on the PS2 console. I attached a picture below to help you... just lift that white disc up and look. I'm sure any tampering/modification isn't 'good' for the BR drive... so just be careful and you should be fine.
