Floppy disk fail (40) or (80) error
Floppy cable not connected properly
Bad floppy cable
If the floppy disk drive appears to be setup properly and the light is not always on, the floppy drive cable may be bad. We recommend getting a new cable from a computer hardware store and purchase a new cable.
If the issue persists, unfortunately it is likely that either the floppy drive is bad or the I/O board or Motherboard is bad. We recommend you contact the computer manufacturer, have the computer serviced or that you replace the floppy drive then the motherboard if the issue persists.
