Everyone should replace their hardware whenever a new model becomes available, but some of us are slackers at supporting the world economy. ;-) The drives are serviceable for reading and burning CD/DVDs, just not so good at reading to EOF. The iso standard defines a format for data on disk that tells the reading software where exactly every datum is. In normal operation there is never any need to test for EOF. Maybe the reason that there is no confusion in more modern hardware is that there is only one factory left in the world actually making these drives, so there is de-facto consensus on how they should operate. -- Paul E Condon pecon...@mesanetworks.net -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
