+           <para>Why does FreeBSD see my disk as smaller than the
+             manufacturer says it is?</para>
+         </question>
+ 
+         <answer>
+         <para>Disk manufacturers calculate gigabytes as a billion bytes
+           each, whereas FreeBSD calculates them as 1,073,741,824 bytes
+           each. This explains why, for example, FreeBSD's boot messages
+           will report a disk that supposedly has 80GB as holding 
+           76319MB.</para>
+         <para>Also note that FreeBSD will (by default)
+           <link linkend="disk-more-than-full">reserve</link> 8% of the disk
+           space.
