Am told somewhere in the ports collection is a utility for exactly that purpose. In the past, if it was a simple single session ISO-9660 disc I'd use cdrecord (SCSI only) to read the size off of the disk, then use dd to read the disk in 2k blocks, with a count of 2 less than cdrecord said. This procedure was able to recreate an exact image of what I had used previously to create the CD-R. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
