Write-protecting Diskettes

You can write-protect a diskette to prevent its data from being
altered. When a diskette is write-protected, you can read it and
copy data from it, but you cannot store new data on it or delete
any files it contains. If you try to change data stored on a
write-protected diskette, you will see an error message.
To write-protect a diskette, turn it over so you are looking at
the underside. Slide the switch in the lower right comer toward
the outer edge of the diskette until it clicks into position,
exposing a hole.
To remove the write protection, slide the switch toward the
center of the diskette until the hole is covered.
