Epson equity 320sx plus Manual De Usuario

On a 3M-inch diskette, the write-protect device is a small
switch on the back of the diskette in the lower right comer,

shown below. To write-protect a 3M-inch diskette, slide the
switch toward the edge of the diskette until it clicks into
position, exposing a hole in the comer.

To remove the write protection, slide the switch toward the

center of the diskette until it clicks into position and the hole
is covered.

Some program diskettes have no notch or switch so they
are permanently write-protected. This protects them from

being accidentally erased or altered.
