makes me think of the bad blocks on the xbox 360 nands, all though, I admit that most electronic stuff is shipped with all ready bad blocks (it's what happens in manufacturing electronics) they make sure they allow enough space on the end of the memory for the "re-mapping" of bad blocks unlike m$ they shipped shit nands. but still they allowed space at the end of the nand I'll give them that.
They just roll out a firmware patch or it will automaticly re-map them, so the next firmware patch might not be all full of dazzling colors or you might even think "what did it do" it was probably telling block 10 to sit in 40, block 20 to sit in 100, then make a table and keep it handy! stand at no 10 any one asking where some block is look down the list and tell them. however you don't normally get firmware updates for memory cards, and they start to get confused with where things are
any one looking for block 10 on the table will now find them in block 40, rather than where they used to be (Block 10), it's a re-mapp bad blocks to the new location, if any one wants to find them look at this chart. as time goes by the chart gets more and more congested, ends up too much and then pttt broken.
You get me, Totally off on one. ha! and talking about bed, adios.
