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.
