Just my $0.02, situations like this are exactly the reason why I keep
a handfull of CDRW blanks around here. So that when I have a problem, or
want to test something I won't be wasting CDRs, even if they are cheap
(especially when I wait til I get 'em on sale with rebates to buy a 
whole bunch). They aren't high-speed, only 4X, but sometimes they'll 
save you from making a pile of coasters.

Not me, sorry. Perhaps Schilly (maintainer of cdrecord, et al) could
if he were to read your plea, as I assume he understands how those
things work! :^)
