Creating an iso on Mac OS X

I know that a lot of you have done this already, but I always forget the best way to create an iso from a cd on the Mac.

I ran across an entry on a forum (http://forums.macrumors.com/showthread.php?t=220740#6) from tgage who gave the following:

From within Terminal (Applications->Utilities->Terminal)

Mac OS X Tiger (10.4)

You can determine the device that is you CD/DVD drive using the following command:

drutil status

Vendor Product Rev
MATSHITA DVD-R UJ-825 DAM5

Type: CD-ROM Name: /dev/disk1
Cur Write: 16x CD Sessions: 1
Max Write: 16x CD Tracks: 3
Overwritable: 00:00:00 blocks: 0 / 0.00MB / 0.00MiB
Space Free: 00:00:00 blocks: 0 / 0.00MB / 0.00MiB
Space Used: 66:55:27 blocks: 301152 / 616.76MB / 588.19MiB
Writability:

Now you will need to umount the disk with the following command:

diskutil unmountDisk disk1

Now you can write the ISO file with the dd utility:

dd if=/dev/disk1 of=file.iso

When finished you will want to remount the disk:

diskutil mountDisk disk1

Thats it.  Just wait for it to finish creating the iso and you are good to go.
