I have a few isos on my hdd and want to sent them to my external hd and I read that Wiiscrubber could reduce the size of my iso. When I scrubbed Metroid Prime 3 and archived it, it reduced the size from 4.37GB to 4.27GB. Is this supposed to turn out like this or is this just a special case? BTW, i saw a scrubbed version of a game that was 500mb. Also, I do not understand the different ways of scrubbing like truncha and hex.
