title: List all drives/partitions, and get /dev/rdisc device with Cocoa
body: <p>Is there a way to list available drives, similar to Disk Utility, and get the associated <code>/dev/rdisk*</code> device for it?</p>
  
  <p>Disk Utility has access to this data - when you select a drive and press the Info button, it lists..</p>
  
  <pre><code>Partition Map Scheme : GUID Partition Table
  Disk Identifier : disk0
  Media Name : Hitachi HTS541612J9SA00 Media
  </code></pre>
  
  <p>..or select a partition:</p>
  
  <pre><code>Disk Identifier : disk0s3
  Mount Point : /Volumes/BOOTCAMP
  </code></pre>
  
  <p>Is there a Cocoa API to get at this? If so, what is the best way to display this via Interface Builder?</p>
