   Oh - some of the things I do is actually speculation on what   
   would be ideal rather than something I'm planning on doing   
   at 3pm tomorrow.   
      
   So to add a dummy sector to an existing HD, all you need   
   is firmware loaded that returns with 512 bytes of data that   
   the HD has no clue about, when LBA 0 or maybe LBA -1 is   
   requested   
      
   If LBA 0 is chosen, the data will need to be unloaded, all   
   the LBA references have 1 added to them, and then the   
   HD is reloaded.   
      
   If anyone complains, I'll ask Jens to bomb them.
