Do SD Cards do built-in wear leveling?  If they do, is it similar to a
journalling translation layer that is built-in to the card so that
everytime a sector is updated, it is internally written to a different
sector transparent to the OS?  Also, is there any protection against
reading bad data from a worn down sector similar to a hard drive
reporting READ ERROR when it reads a sector which fails a CRC check?
