Write–Protecting 3.5–Inch Diskettes
Write–protecting diskettes is necessary so that important information is not accidentally lost.

To locate the write–protect tab, turn the diskette over with the label facing down.
• To prevent writing onto a diskette, slide the write–protect tab to open the protect slot, as
shown in the following illustration.
• To allow writing onto a diskette, slide the write–protect tab to cover the protect slot, as
