Hey, this is a total noob question, so bare with me... I've been on the hunt for a complete 1:1 iso of Metroid Prime Trilogy. I used cleanrip to make an iso off my disk. I then combined the 2 isos that were created with Wii BackUp Manager. I checked the complete iso's properties, on "size" it lists "7.92 GB (8,511,160,320 bytes)", but on "size on disk" it lists "7.59 GB (8,157,921,280 bytes)". All my other isos "size" and "size on disk" match. Did I do something wrong? is my rip of the Metroid Trilogy good?
