   I thought sector size was a hard drive physical property and not   
   something that could easily be adjusted.  Thus there is effectively no   
   need to look it up.   
      
   As I understand it, there are two vastly predominant sector sizes; the   
   venerable 512 bytes and the new 4096 bytes (8 x traditional 512 bytes).   
   All drives that have sectors larger than 512 are multiples of 512 and   
   have virtual 512 sectors for backwards compatibility.
