Appendix E
You need to make a copy of the essential system software for safekeeping in
case you ever need to reinstall the software on your computer. The disks you
need to install and reinstall software are called installer disks. You use the
Floppy Disk Maker application program to create your system software
installer disks.
What is a disk image?
A disk image is a discrete electronic representation of an individual disk.
The Disk Images folder in the Floppy Disk Maker folder on the computer’s
hard disk contains the disk images you need to create installer disks for your
system software. 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.
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.
