How a Floppy Drive Works
Floppy drives have two primary connectors, a ribbon cable
called the data cable, and a power connection to the power
supply. The ribbon cable connects the back of the floppy drive
with the floppy controller port J5 on the mainboard. Data ribbon
cables often have two connectors. If you have more than one
floppy drive on your system, they often share the same ribbon
cable.
The data cable also has a red stripe. Whenever connecting or
disconnecting the ribbon cable, be sure to attach the cable
connectors so the red stripe is pointing toward pin 1 of the
connector. Pin 1 is often labelled with a small triangle or filled in
corner.
