I'm currently doing the HDD method since games load faster and no stress on the lense. Not all games work for HDD method unless rebuild with the right tools ex: cdgen, apache, nero, dvd disk, etc... If you have a newly fresh HDD, you don't nee to format it, HDAdvance or HDLoader will do it automatically If not, get the newest elf and it'l give you an option to format the HDD. blaaahhh...just go here http://www.sksapps.com/index.php?page=hd.html
