How to install a IDE Hard Disk Drive
If you look at the rear side of an IDE hard drive it should look similar to the image below.
The IDE/ATA connector is on the left hand side which consists of many pins. Next to the IDE connector is the jumper setting for the drive. The jumper should be set to Master, which is the default setting for a new HDD. Any other device sharing the same IDE cable should be set to Slave. Different HDD has different jumper settings, please refer to your HDD manual for more information. On the right hand side, next to the jumpers is the power connector. Every device except FDD uses this type of power connector.
Figure 1 and 2 below shows what an ATA 66 and a power cable looks like. The ATA 66 cable which is also known as UDMA 66 cable is an advance IDE cable, which offers higher performance and data integrity than the standard IDE cable. ATA 66 cable consists of 80 conductor cable where as the standard IDE cable consists of 40 conductor cable. I am using an ATA 66 cable because the above HDD is an ATA 100 drive which requires an ATA 66 cable.
