title: How can I determine the sector size in windows?
body: <p>How can I determine the <strong>Physical Sector Size</strong> (e.g. if i have an <a href="http://en.wikipedia.org/wiki/Advanced_Format">Advanced Format</a> drive with 4,096 byte sectors rather than the legacy 512 byte sectors) in Windows 7?</p>
  
  <p>I know that by clicking on a file and get properties we can find out the NTFS <em>Cluster Size</em>, but that's not the same as the hard-drive's <em>sector</em> size.</p>
  
  <p><strong>Note</strong>: We ask about Windows 7 because it (and Windows Vista SP1) understand the existence of 4096 Advanced Format hard drives.</p>
