Without knowing anything about the internals of the cd drivers I can confidentally assume that all cdrecord does is use a few driver specific ioctls to put the driver (& device) into an appropriate mode then issues write(2) system calls - which is pretty much all dd will do. So if the device is in the correct mode dd will do fine. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
