YAFFS tracks bad blocks by scanning for bad block markers at boot time. These 
blocks are then not used.
Any errors on blocks that occur during runtime are flagged. When the block is 
garbage collected, the data is copied off and instead of erasing and 
recycling the block it is marked bad and never used again.
