   	A standard floopy has:   
   	80 tracks with 9 sectors of 512 bytes on each side, so it is a total of:   
   	80*9*2*512 = 737 280 bytes.   
      
   	Some sectors are reserved for boot + FAT, so you only get 726 016 bytes   
   available for storage.   
      
   	738260 - 737280 = 980 bytes added.   
   	Well, I can't say more in this organisation of those 980 bytes.   
      
   	Guillaume.
