You may already have a diskette in the drive. Make sure the drive is 
empty.

You may be inserting the diskette incorrectly. Hold the diskette with

label side up. Close the tray carefully, making sure it has shut 
completely.

Make sure the computer is connected to a power source and turned 
on. The optical disc drive eject mechanism requires power to 
operate.
