Please note that this is not cdrecord but a defective fork where someone
did rip off the working DVD support from the cdrecord original source and 
replaced it with something half baken. Wodim (this is what you used)
does not retrieve information about the medium and this is why it is
very probable that wodim fails when trying to send a SCSi command that is
related to the actual free size on the medium.

It is very likely that this problem does not occur with the original
cdrecord from:

ftp://ftp.berlios.de/pub/cdrecord/alpha/

I've seen similar reports before in the net and reports from users that
reported success after upgrading to the original software.
