Epson EQUITY 386SX/16 PLUS - Manual (Page 65)

On a diskette, the write-protect device is a small
switch on the back of the diskette in the lower right corner,
shown below. To write-protect a
diskette, slide the
switch toward the edge of the diskette until it clicks into
position, exposing a hole in the corner.

To remove the write protection, slide the switch toward the
center of the diskette until it clicks into position and the hole
is covered.
Note
Some program diskettes have no notch or switch so they
are permanently write-protected. This protects them from
being accidentally erased or altered.
