Creating a disk image of a device, folder, or volume

You can use Disk Utility to create an image of a single device, folder, or volume. You can use the disk image to transfer files from one computer to another, or burn the image on a CD or DVD disc that you can use to restore the contents of another disk.

If you want to create a disk image of files that are in different locations, gather them into a single folder or onto a single volume before you begin.

You can create a full disk image that uses the same amount of disk space as the disk it represents, or create a sparse disk image that includes only the data on the disk. For example, a 10MB disk may have only 5MB of data. A full disk image would be 10MB, while a sparse disk image would be 5MB.

Open Disk Utility, located in Applications/Utilities.
If you're creating a disk image from a folder, choose Images > New > "Image from Folder." Then select the folder you want from the navigation window.

If you're creating a disk image from a device or volume, select it in the list on the left side of the Disk Utility window, then choose Image > New > "Image from [disk or volume name]."
Type a name for the image, and choose a disk format.
Choose Encryption, if desired, then click Save.

The name of the disk image is followed by the filename extension ".dmg.

Would have been even faster if you'd checked the 'Help' on your Mac first. ;)
