Copy DVD Disk to an File From OSX Command Line PDF

Let's say you have a DVD that you want to backup and you've tried to copy files from it but some files cannot be copied because the DVD is cratched and it returns you read errors. If files that cannot be read entirely are video files you can still copy those file partially by ignoring read errors.

To copy/backup a DVD from OSX and ignore errors we will use dd command from OSX's terminal:

  sudo dd if=/dev/disk1 of=file.img bs=1m conv=noerror,notrunc
