-	<answer>
-	  <para>The &man.ata.4; driver reports <errorname>UDMA
-	    ICRC</errorname> errors when a DMA transfer to or from a drive
-	    is corrupted.  The driver will retry the operation a few
-	    times.  Should the retries fail, it will switch from DMA to
-	    the slower PIO mode of communication with the device.</para>
-
-	  <para>The problem can be caused by many factors, although
-	    perhaps the most common cause is faulty or incorrect
-	    cabling.  Check that the ATA cables are undamaged and rated
-	    for the Ultra&nbsp;DMA mode in use.  If you are using
-	    removable drive trays, they must also be compatible.  Be
-	    sure that all connections are making good contact.  Problems
-	    have also been noticed when an old drive is installed on the
-	    same ATA channel as an Ultra&nbsp;DMA&nbsp;66 (or faster)
-	    drive.  Lastly, these errors can indicate that the drive is
-	    failing.  Most drive vendors provide testing software for
-	    their drives, so test your drive, and, if necessary, back up
-	    your data and replace it.</para>
-
-	  <para>The &man.atacontrol.8; utility can be used to show and
-	    select the DMA or PIO modes used for each ATA device.  In
-	    particular, <command>atacontrol mode
-	    <replaceable>channel</replaceable></command> will show the
-	    modes in use on a particular ATA channel, where the primary
-	    channel is numbered 0, and so on.</para>
