5. Connecting IDE and Floppy Drives

The colored stripe on a ribbon cable should face toward the keyboard connector. In Figure 2-9 on the previous page, you can see how the IDE cables should look when they are connected to your hard drive. Notice how Pin 1

(denoted by a red stripe) isPin 1 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 harddrive. Figure 2-10 shows the IDE cable properly connected to the motherboard. Contact your hard disk drive manufacturer or documentation for more information.

ATA-66 IDE hard drives require a special IDE cable which has additional grounding wires. The cable is sold separately, and is required when using ATA-66 drives. This cable will also support all legacy IDE drives.

Some symptoms of incorrectly installed HDDs are:

•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: bad IDE cable or defective drives/ motherboard. Try another HDD.

•Hard drives do not power up: check power cables and cabling. May also be caused by a bad power supply or IDE drive.
