Creating a blank DOS-format disk

format—either Macintosh or DOS.

1 Insert a floppy disk.
m If the disk has not been initialized, a dialog box appears in which you can
specify the disk’s name and format.
m If the disk has already been used, you’ll need to erase it. Select the disk,
then choose Erase Disk from the Special menu.
WARNING Before you erase or initialize a disk, be sure that the disk
contains no information you want to save.
