Hacking Just did a BootMii NAND restoration, now got some questions.

[HNKii]

During the 'emulated' restore, I noticed that some blocks are skipped, and when the real restoration started, it skipped the blocks that are also skipped in the previous process.
What are those skipped blocks? Are they empty or do they hold identical data as the corresponding blocks in the System/NAND dump?
Thank you for helping.

I think their the remapped bad blocks.
Atleast, that would make sense.

They don't seem to be bad blocks only. My Wii only has 10 bad blocks but there were 50+ empty blocks.
