5. Connecting IDE and Floppy Drives

The colored stripe on a ribbon cable should face toward the ATX Power Connector on
the motherboard. In Figure 2-8 (below), you can see how the IDE cables should look
when they are connected to your hard drive. Notice how Pin 1 (denoted by a colored
stripe) is connected so that it is next to the power connector of the drive. The primary
IDE connector is black; the secondary IDE connector is white. In most cases, this is
the proper way of connecting your IDE cable to the hard drive. Figure 2-9 on the next
page shows the IDE cable properly connected to the motherboard. Contact your hard
disk drive manufacturer or documentation for more information.
Figure 2-8
ATA-66/100 IDE hard drives require a special 80 pin IDE cable which has additional
grounding wires. The cable is included in the motherboard package, and is required
when using ATA-66/100 drives. This cable will also support all legacy IDE drives.

(Note: The BLUE end of the ATA-66 cable must connect to the motherboard.)
Some symptoms of incorrectly installed HDDs are:
important!
• Hard disk drives are not auto-detected: may be a Master / Slave problem or a bad
IDE cable. Contact your vendor.
• Hard Disk Drive Fail message at bootup: may be a bad cable or lack of power
going to the drive.
• No video or beeps on bootup: usually means the cable is on backwards.
• Hard drive lights are constantly on: usually means bad IDE cable or defective
drives / motherboard. Try another HDD.
• Hard drives do not power up: check power cables and cabling. May also be a bad
power supply or IDE drive.
