What is a disk image?
A disk image is a discrete electronic representation of each individual installer
disk. The Disk Images folder in the Floppy Disk Maker folder on your hard
disk contains the disk images you need to creater installer disks for both your
system software and the other software that comes on the hard disk. When
you use Floppy Disk Maker, it copies the disk images onto floppy disks. When
you are finished making a set of disks with Floppy Disk Maker, you’ll have a
set of installer disks and will be able to reinstall the software that comes on
your computer.
Note: You must use the Floppy Disk Maker program to create your installer
disks. (Although you can copy the disk images onto floppy disks by dragging
the files, you won’t be able to install the software from those disks because
the disk images are compressed files.)
What you need
Just as you need paper to make copies of important documents, you need
floppy disks to make copies of the information on your hard disk. You can
probably buy the floppy disks at the same place you bought your computer.
Floppy disks come in a variety of sizes and capacities. The ones you need for
backing up your hard disk are called high-density 3.5-inch disks. You can
recognize the disks by the way they look:
Even though these disks have a hard plastic casing, they are called “floppy
disks” because the disk inside the casing is floppy.
High-density disks
have two holes...
...and they have
this symbol.
