Floppy Data Cables

The floppy drive data cable has a 34-pin connector. Like the PATA data cable, the floppy drive data cable has a stripe to denote the location of pin 1. A floppy drive data cable usually has three 34-pin connectors. One connector at the end of the cable connects to the motherboard. The other two connectors connect to drives. If multiple floppy drives are installed, the A: drive connects to the end connector after the twist in the cable. The B: drive connects to the middle connector.

Plug the floppy drive data cable into the drive with the pin 1 indicator on the cable aligned to the pin 1 indicator on the drive connector. Motherboards have one floppy drive controller, which provides support for a maximum of two floppy drives.

Note

If pin 1 on the floppy drive data cable is not aligned with pin 1 on the drive connector, the floppy drive will not function. This misalignment will not damage the drive, but the drive activity light will display continuously. To fix this problem, turn off the computer and reconnect the data cable so that pin 1 on the cable and pin 1 on the connector are aligned. Reboot the computer.

    What does a twist in a 34pin data cable mean?
    2 months ago
  • A twist in a 34-pin data cable means that the wires within the cable are twisted together in order to reduce the amount of electromagnetic interference that is present in the cable. The twisting helps prevent adjacent wires from interfering with each other, thus improving the signal quality of the cable.
