I'm aware of the benefits of using WiiScrubber, my question lies in the potential problems with using it on a 1:1 .iso. If I understand this correctly it changes the garbage data in a separate partition of the disk meant to fill the disk to the 4.7 gigs. Is there any potential loss of valuble data? Is this causing any of the read errors / green screens? If not, why isn't every .iso you see scrubbed?!?
