[QUOTE="gatorparrots, post: 181"] If you need to create a personal backup copy of a CD-ROM or DVD, it's fairly simple to do so in the terminal. First, insert the CD-ROM/DVD to be copied into your drive. When the Finder mounts it, take note of the path (especially the title of the disc). [i](You can also get this information via [b]df[/b] if you are working totally without the GUI.)[/i] Next, unmount the disc: [color=blue]hdiutil unmount "/Volumes/nameofcd"[/color] It should report its progress like so: [code]hdiutil: unmount: LetIOKitSettleDown: (timed out). "disk3s1s9" unmounted successfully.[/code] Next, copy the disc to your hard disk using the CD/DVD Master format (use whatever disk3xxxx name was returned above in the following command): [color=blue]hdiutil convert /dev/disk3s1s9 -format UDTO -o "~/Desktop/nameofcd"[/color] Its progress will look something like this: [code]Preparing imaging engine... Reading Apple_HFS (0)... .......................................................................... Terminating imaging engine... Elapsed Time: 17m 21.578s (2 tasks, weight 100) File size: 678428672 bytes Sectors processed: 1325056, 1325056 copied Speed: 636.1Kbytes/sec created: nameofcd.dmg[/code] Eject the disc from the drive and run this command: [color=blue]hdiutil burn "nameofcd.dmg" -noverifyburn -noeject[/color] It will prompt you for a disc, insert one and it will burn your disc:[code] Please insert a disc: Starting Initializing Saving temporary image Opening session Writing track ............................................................................ Finishing writing ............................................................................[/code] [/QUOTE]
