Some CD/DVD readers handle EOM differently than others. For "fun" use the same dd command on the copied CD and compare it to the output of the first dd from original. I suggest Jonathan install sysutils/cdrtools from ports (if not already installed) and use the readcd(1) utility which is part of that collection. Its a bit of a hassle if your DVD/CD is ATAPI as the atapicam(4) SCSI/ATAPI translation layer needs to be added to your kernel. readcd(4) knows a bit more about what it is reading than dd so it does a better job. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
