 <title>Checking the hard disk</title>
  <p>Hard disks have a built-in health-check tool called <app>SMART</app> 
 (Self-Monitoring, Analysis, and Reporting Technology), which continually 
 checks the disk for potential problems. SMART also warns you if the disk 
 is about to fail, helping you avoid loss of important data.</p>

  <p>Although SMART runs automatically, you can also check your disk's 
 health by running the <app>Disk Utility</app> application:</p>

<steps>
 <title>Check your disk's health using the Disk Utility application</title>
 
 <item>
  <p>Open the <app>Disk Utility</app> application from the <gui>Activities</gui>
  overview.</p>
 </item>
 <item>
  <p>Select the disk you want to check from the <gui>Storage Devices</gui> list.
  Information and status of the disk will appear under <gui>Drive</gui>.</p>
 </item>
 <item>
  <p><gui>SMART Status</gui> should say "Disk is healthy".</p>
 </item> 
 <item>
  <p>Click the <gui>SMART Data</gui> button to view more drive information, or
  to run a self-test.</p>
 </item>

</steps>

 <title>What if the disk isn't healthy?</title>

  <p>Even if the <gui>SMART Status</gui> indicates that the disk <em>isn't</em> 
 healthy, there may be no cause for alarm. However, it's better to be prepared 
 with a <link xref="backup-why">backup</link> to prevent data loss.</p>

  <p>If the status says "Pre-fail", the disk is still reasonably healthy but 
 signs of wear have been detected which mean it might fail in the near future. 
 If your hard disk (or computer) is a few years old, you are likely to see 
 this message on at least some of the health checks. You should 
 <link xref="backup-how">backup your important files regularly</link> and check 
 the disk status periodically to see if it gets worse.</p>

  <p>If it gets worse, you may wish to take the computer/hard disk to a 
 professional for further diagnosis or repair.</p>
