The canonical answer from the handbook is Duplicating Data CDs You can copy a data CD to a image file that is functionally equivalent to the image file created with sysutils/mkisofs, and you can use it to duplicate any data CD. The example given here assumes that your CDROM device is acd0. Substitute your correct CDROM device. A c must be appended to the end of the device name to indicate the entire partition or, in the case of CDROMs, the entire disc. # dd if=/dev/acd0c of=file.iso bs=2048 Now that you have an image, you can burn it to CD as described above. http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-cds.html#IMAGING-CD -- Lowell Gilbert, embedded/networking software engineer, Boston area: resume/CV at http://be-well.ilk.org:8088/~lowell/resume/ username/password "public"
