title: robocopy /b access denied
body: <p>I'm going nuts over Robocopy. I want to create a 1:1 exact copy (including data, and permissions of each file &amp; folder) of two local volumes.  Actually, they are located on different physical HDD's. Say I have <code>A:\</code> and <code>B:\</code>.  I just want to copy all of the stuff from <code>A:\</code> to <code>B:\</code>.</p>
  
  <p>So, I tried this command:</p>
  
  <p><code>robocopy A:\ B:\ /e /b /copyall /dcopy:T</code> </p>
  
  <p>But I keep getting access denied errors.  Same results with <code>/zb</code> switch.  I am using elevated/admin privileges in Win7 to run the Robocopy commands in command prompt.</p>
  
  <p>I found a Microsoft hotfix, which fails to install on my machine, not sure if it would remedy my problem (KB979808).</p>
  
  <p>I don't know if the problem is the commands, Robocopy itself, or the operating system.</p>
  
  <p>Any ideas?</p>
