Caution
Never turn on your computer with a protective card in the
diskette slot. You could damage the diskette drive.
If you have a second 5.25-inch diskette drive, be sure to remove
the card from it also.
Save the protective card. If you transport your computer later,
insert the card to protect the drive’s read/write heads during
shipping.
