>Description:
Recently, I often saw (and answered) a specific question about
burning CDs on -question. Users tended to burn raw files (for example
tarballs) to CDs, and then wondered why they couldn't mount the
CD under FreeBSD or access the data on it under a different
operating system. Although there is a chapter about burning CDs in
the handbook, I prepared a FAQ entry that explains how such
"raw" CDs are to be used, and how to actually create a "real"
ISOFS CD then can be mounted under FreeBSD and is also
accessible under other operating systems.
>How-To-Repeat:
Read the -questions archives and count how often this
question was added during the last few weeks...

+ <question id="burncd-isofs">
+ <para>I burned a CD under FreeBSD and now I can not read it under any other operating
+ system. Why?</para></question>
+
+ <answer>
+ <para>Most likely, you burned a raw file to your CD, probably by using a command
+ like:</para>
+
+ <screen>&prompt.root; <userinput>burncd -f /dev/acd1c -s 12 data archive.tar.gz fixate</userinput></screen>
+
+ <para>CDs are sometimes burned that way, espeically for backup purposes.
+ In order to retrive the data burned to the CD in the above manner, you'd have to use
+ a command like:</para>
+
+ <screen>&prompt.root; <userinput>tar xzvf /dev/acd1c</userinput></screen>
+
+ <para>If you want to be able to mount your CD under FreeBSD or use it under a different
+ operating system, however, this method will not work. Instead, you will have to create
+ an ISO 9660 filesystem from the files to be burned to your CD first. In order to do that,
+ you will first have to install the <filename>sysutils/mkisofs</filename> port. Once that
+ has been done, you can issue a command like:</para>
+
+ <screen>&prompt.root; <userinput>mkisofs --allow-lowercase --allow-multodot -r -o cdimage cddir</userinput></screen>
+
+ <para>This will create a file named <filename>cdimage</filename> from all files in the
+ <filename>cddir</filename> directory. You can then do:</para>
+
+ <screen>&prompt.root; <userinput>burncd -f /dev/acd1c -s 12 data cdimage fixate</userinput></screen>
+
+ <para>The resulting CD can be mounted under FreeBSD like any other normal CD, and it will work
+ under other operating systems as well.</para>
