Hey guys, as requested, here is the tutorial for upgrading your PS3 HDD. Remember that before you start these steps you need to back up all your data that you want saved. That means, game saves, music, and pictures. No need to back up your game downloads, settings, or friends lists. All that is saved in your flash memory.Once you have backed everything up onto a thumb drive, server , or USB Hard Drive, you are good to go.
If the HDD you are using to replace the old one is out of another machine, don't worry about formatting it. The Playstation3 will do that once the system initializes on first start up. But if you are paranoid about data leak, go ahead and wipe it clean.
