2-6 Connecting Parallel, Floppy and Hard Disk
Drives
Use the following information to connect the floppy and hard disk
drive cables.
• The floppy disk drive cable has seven twisted wires.
• A red mark on a wire typically designates the location of pin 1.
• A single floppy disk drive ribbon cable has 34 wires and two
connectors to provide for two floppy disk drives. The connector
with twisted wires always connects to drive A, and the connec-
tor that does not have the twisted wires always connects to
drive B.
• An IDE hard disk drive requires a data ribbon cable with 40
wires, and a SCSI hard disk drive requires a SCSI ribbon cable
with 50 wires.
• A single IDE hard disk drive cable has two connectors to
provide for two drives. To select an IDE disk drive as C, you
would normally set the drive select jumper on the drive to DS1.
To select an IDE disk drive as D, you would normally set the
drive select jumper on the drive to DS2. Consult the documen-
tation that came with your disk drive for details on actual
jumper locations and settings.
• A single SCSI ribbon cable typically has three connectors to
provide for two hard disk drives and the SCSI adapter. (Note:
most SCSI hard drives are single-ended SCSI devices.) The
SCSI ID is determined by jumpers or a switch on the SCSI
device. The last internal (and external) SCSI device cabled to
the SCSI adapter must be terminated.
• Some drives require a special controller card. Read your disk
drive manual for details.
