   So you became a hard disk manufacturer yet?   
      
   ATA PIO mode supports LBA48 (2^48 sectors)   
   =281.14749767E12 sectors, *512 = 144E15 byte   
   =128000 TB (or call that 128 HB if you like).   
   this 4K sectors joined in for lower costs and   
   speed reasons, it wasn't a size issue.
