    how do I know if it is scrubbed or unscrubbed when I download it ? Does that mean if I zip it and it show about 1.30 gb in zip then it is scrubbed and if it is about 3gb in zip then it is scrubbed ? or is there a program that can tell me by identity of it is scrubbed or unscrubbed ? Thanks.

    I have no idea if there is a program that does this, but I know that Scrubbed releases are notably smaller.

    An easy way to tell is to open up an iso in a hex editor, then go to the end of the file.

    If you see FFs or 00s (or the same byte over and over again), then it is scrubbed.

    If you see random garbage data it is most likely not scrubbed.

    I tried windhex32 but all of it are OOs.. all of it.

    Does it mean anything if I zip it and it show 1.29gb the its scrubbed or it doesnt matter because it could be unscrubbed too ?

    If it's unscrubbed, it'll remain around 4.38GB (might compress by 1-2% to 4.3GB) - if it's scrubbed it'll compress significantly.

    Seems to me that the 1.29GB iso you're talking about is scrubbed.

    Wiiscrubber does have an unscrubbing ability, but you will also require the original garbage data in a separate file for wiiscrubber to use, else you cannot unscrub it.

    A handful of retail games appear as scrubbed (indeed them appearing is what kicked scrubbing off in the first place) or at least without the random padding between files.

    What SanGor says is 50/50- the scrubbed sections are not hashed as such (the main reason it works) but some later scrubbers and methods can shift and delete things which will break said hashing (also earlier/more intense methods wipe out everything while others leave initial sections intact at the cost of some space- nothing has checked these that I am aware of though).

    Otherwise as hunnymonster says- most retail games have random data in the sections that would be scrubbed and with the rest of it being "encrypted" it will only compress a tiny amount.

    open the ISO up in WiiScrubber, normally scrubbed release only have partition0 - the game and no date partition(which would be partition0 and the game partition1)
