mkisofs, mount, md5sum
Before you burn a data CD in Linux, you need an ISO image – mkisofs
helps you create an Iso image. To save disks, you might like to check
the image before you burn it with md5sum.
CDs and disk partitions use different
filesystems. Whereas Linux
may use the Ext3 or ReiserFS format
for partitions, CDs use the ISO9660
filesystem. It doesn’t make much sense
to burn a partition block by block onto a
CD. Instead, you will need to run the
mkisofs tool first to create an ISO9660
filesystem where you can store the
required files. Having done so, you can
burn the “ISO image” onto disk using
the cdrecord tool.
This issue of Command Line takes an
in-depth look at command line tools for
burning and verifying CD images.
