  I haven't seen any clear correlation between age and vulnerability.  
Old Samsung SCR-2432 and SCR-3232 CD drives from 8-year old boxes aren't 
vulnerable.

  I've seen technical articles (which I don't fully understand) 
explaining the many reliability advantages of the plus format over the 
minus.  I always use plus.  It's no more expensive anyway.

  But what about command-line cdrecord?  K3B and other graphical tools 
all probably choose automatically between cdrecord and growisofs, and 
I'm guessing that with DVDs they always use growisofs.
