Choose a size for your disk image and a volume format,
which is Mac OS X Extended (Journaled) by default.
?– Encryption Encrypting your disk image is a security feature designed to prevent
unauthorized viewers from accessing the data on it.
?– Partitions Choose a partition type from the options available. Choose the best option
to suit your intentions for the data. For instance, if you plan to burn the data to a CD or
DVD, choose CD/DVD as the Partitions option.
?– Image Format Choose which format to use for your disk image.
Once you??™ve determined the
settings for your new disk image,
click the Create button. The new
disk image appears in the directory
you saved it to, as well as in the
source list of Disk Utility, as
shown here.
The disk image also appears
on your desktop, but notice that
there are two icons! ???What??™s up
with that? I only created one disk
image!??? The icon for the disk
image itself looks like a piece of
paper with a hard drive icon on it,
as is illustrated by diskimage.dmg
in Figure 23-2. When a disk image
is opened, or mounted, it displays
its volume icon, which looks like a
slot-loading drive of sorts (see Disk Image, also in Figure 23-2).
