Hacking Another bad block question

[thesund0g]

Hey guys, I have a couple of questions about the Wii's NAND.

First, out of sheer curiousity, do the bad blocks on the NAND get mapped out at the NAND plant or Nintendo's?

Now, as the Wii is running, does it at any point actually recheck for bad blocks, during format or otherwise? I'm wondering what will happen as a few chips will fail prematurely. Fortunately, we have SNEEK to prevent this from being a huge problem, but I wonder what will happen to the folks not running it.

Edit: I remember the HackMii installer does something with bad blocks as it does a NAND dump, but I don't remember what, can someone remind me?
