Does it matter whether I use a CD or DVD?
The type of disc you use depends on how much data is in the disk image. Most CDs can
hold a maximum of about 700MB of data. If your disk image contains more than 700MB,
you need to use a DVD. Single-layer DVDs hold up to 4.7GB (single-sided) or 9.4GB
(double-sided); double-layer DVDs hold up to 8.5GB (single-sided) or 17GB (double-
sided).
How do I know how much data is in my disk image?
The easiest way to find out how much data is stored in a disk image is to mount it in Disk
Utility, select it, and then read the Total Capacity value near the bottom of the Disk Utility
window.
