   If you Quick Format a partition, there is only sufficient time   
   (ten seconds), to erase the metadata and lay down empty metadata   
   structures. There is no time during a Quick Format, for a   
   read-verify of the platter surface.   
      
   Reading the surface of a disk drive and certifying it is functional,   
   takes hours to do. It is a very slow process.   
      
   That's why we don't do this check very often, it takes a long time   
   to do it. It takes longer than the time to do a backup .
