Figure 3-1. Write-protect notch
On a diskette, the write-protect device is a small switch on the
lower-right corner on the back, shown in Figure 3-2. To write-protect this
diskette, slide the switch down toward the edge of the diskette so there is a
hole where the switch used to be. To write to a diskette, move the
switch up toward the center of the diskette so the hole is covered.
