Chapter 16. Formatting and Copying Flopp... > Reusing Disks Without Losing Data - Pg. 152

Formatting and Copying Floppy Disks and Recordable CDs 152 When formatting a disk, make sure you format to the disk's capacity not the drive's capacity; oth- erwise, you might lose data you try to store on the disk. (The disk's capacity should be marked on the disks or on the box that the disks came in; HD indicates "high density" or 1.44MB; DD indicates "double density" or 720KB.) Techno Talk Formatting divides a disk into small storage areas and creates a file allocation table (FAT) on the disk. When- ever you save a file to disk, the parts of the file are saved in one or more storage areas. The FAT functions as a classroom seating chart telling your computer the location of information on all of the disk's storage areas. You can format disks using either My Computer or Windows Explorer. I prefer using My Computer because it's lying there right on my desktop. Just insert the unformatted disk and double-click its icon in My Computer or Windows Explorer; Windows displays a series of dialog boxes to lead you through the rest of the process, as shown in Figure 16.1. If My Computer displays the contents of the disk (or a blank window if the disk has no files on it), the disk is already formatted.
