Yes. cdrskin uses its fifo to peek at the first few kB of the image. growisofs does it similar. That is necessary only for write mode DAO of DVD-R[W] and SAO of CD-R[W]. With the multi-session capable mode Incremental of DVD-R one can just start writing. DVD+R and BD-R behave about the same. DVD-RAM, DVD+RW, BD-RE can be freely written in random access with 2 or 32 kB granularity. DVD-RW can be switched between DVD-R behavior and DVD+RW behavior.

But cdrecord and wodim should be able to do this on CD by option -tao.

It is willing to burn CD, DVD and BD. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to cdwrite-requ...@other.debian.org with a subject of "unsubscribe". Trouble?
