Write-protecting diskettes

It's easy to write-protect a diskette to prevent its data

from being altered. When a diskette is write-protected,

you can read 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, you get an error message.

To write-protect a diskette, just cover the small,

rectangular notch with an adhesive write-protect tab.

These write-protect tabs usually come in the box with

new diskettes when you buy them.

If you change your mind and want to write to a

diskette, remove the write-protect tab.
