Hi,

This is an anti-piracy feature included on some discs. Nowadays there
are more and more protected discs around. Some of them even crash
computers when loading. How silly is that? Programs like CloneCD can
handle such things on Windows boxes. That is what I use after having
long frustrated sessions with open-source tools.

Cheers,
Mikhail.
