<para>How can I create an image of a data CD?</para>
</question>
<answer>
<para>If you want to make a bit-by-bit copy of a CD (so you
can, for example, duplicate it with a CD burner), use
&man.dd.1;. The example given here assumes that you have
a IDE CDROM device that shows up as
<devicename>acd0</devicename>. If you have a SCSI CD
or different type of drive, you will want to substitute
the correct device name. A <literal>c</literal> must be
appended to the end of the device name, indicating
the entire partition, or in the case of CDROMs, the entire
disc.</para>
<screen>&prompt.root; <userinput>dd if=/dev/acd0c of=file.iso bs=2048</userinput></screen>
<para>The file generated will be a standard ISO file, which
can be used with <application>cdrecord</application>,
<application>burncd</application>, or any other program
supporting this standard CD data format. This method does
not work with audio CDs.</para>
<para>For more on working with CDROMs, see the
<ulink url="../handbook/creating-cds.html">Creating
CDs Section</ulink> in the Storage chapter
in the Handbook.</para>
