11. CDs, DVDs, and iTunes > Burning CDs and DVDs

Burning CDs and DVDs

If your Mac can burn CDs or DVDs, you’ve got yourself the world’s most convenient backup system. It’s just like having a floppy disk drive—except that a blank CD holds at least 450 times as many files, and a blank DVD holds about 3,250 times as many!

You can buy blank CDs very inexpensively in bulk—$20 for 100 discs, for example—via the Web. (To find the best prices, visit www.shopper.com or www.buy.com and search for blank CD-R.) Blank DVDs are more expensive—about $30 for 50 (at www.cdrdvdrmedia.com, for example)—but that’s not ridiculous, considering their capacity.

Up to Speed: Mac OS Extended Formatting

Whether you use Disk Utility to erase a disk (or when you first install Mac OS X and elect to erase the hard drive in the process), you’ll be confronted with a choice between formatting options called Mac OS Extended and UNIX File System (UFS). (Depending on the kind of disk, you may also see an option to create a DOS-formatted disk for use in Windows machines.)
