Please try to run cdrecord on a different OS (e.g. Solaris or Win32).
Your mail does not include any hint to the problem but other similar
reports make it highly probable that this is caused by a bug in the Linux
kernel.
There are well known reports that verify that Linux under some conditions
bastardizes the "blank" command before sending iit to the drive. I myself
did see Linux bastardizing the "read toc" command. In my case, booting the
same hardware with Solaris or SCO Unixware did solve the problem.
