title: Not getting UUID from diskutil on OSX
body: <p>Running Mac OSX 10.7.5
  I want to enable NTFS on a USB3 external hard disk and need the UUID to do it (<a href="http://ntfsonmac.com" rel="noreferrer">http://ntfsonmac.com</a>) but diskutil is refusing to give me the UUID. I start with:</p>
  
  <pre><code>diskutil info /Volumes/HD-PCTU3/
  </code></pre>
  
  <p>then from this:</p>
  
  <pre><code>diskutil info disk2s1
     Device Identifier:        disk2s1
     Device Node:              /dev/disk2s1

  <p>but as can be seen there is no UUID displayed. Any ideas why and/or how to get the UUID?</p>
