Note: You need to format your blank diskettes before you can use them
with your operating system. Refer to your MS-DOS or other operat-
ing system manual for instructions on how to format your blank
diskettes.
There are two ways to avoid losing the valuable information stored on
your disks; write-protect your diskettes and make backup copies. Both of
these methods are described below.
Write-protecting diskettes
You can write-protect a diskette to prevent its data from being altered.
When a dikette is write-protected, you can copy data from it, but you cannot
store new data on the diskette or delete any files it contains. If you try to
change data stored on a write-protected diskette, an error message displays.
To write-protect a 5%” diskette, cover the small, rectangular notch-
shown in Figure 2-4, with an adhesive write-protect tab. Write-protect tabs
usually come with new 5%” diskettes when you buy them.

To unwrite-protect a 5¼” diskette, remove the write-protect tab.
On a 3½” diskette, the write-protect device is a small switch on the
lower-right corner on the back, shown in Figure 2-5. 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.
