Drive to Drive -- Understanding how IDE Cables work
You may call it an Integrated Device or Drive or just an IDE. IDE Cables are used to connect two drives together. These cables are usually connected with the assistance of jumpers which are situated on the rear of a drive. The top drive is called the “master” drive and the bottom drive is called the “slave” drive. The master drive is naturally the primary drive. It is usually placed at the end of a two connection IDE cable. The secondary or slave drive is attached to the IDE cable between the primary drive and the motherboard IDE connection. It is not possible to transfer data from each drive simultaneously in effect creating two master drives.
IDE Cables include either 40 individual wires or 80 individual wires. Unfortunately, people started experiencing various problems and unusual issues crop up by using 40-conductor IDE cables because of its older and weak design. The speed of IDE/ATA interface is also very low. Current devices including the Ultra ATA/66 need 80 pin wire cables to work faster. People may be wondering on the introduction of 40 extra wires in a cable. However, the extra 40 wires do not carry any additional information except they are just there to split the original 40 signal wires, in an effort to reduce intrusion and other signalling problems linked with higher-speed transfers. So the 40 additional conductors are allied to the grounding and intermingle between the initial 40 conductors of the previous cable. Any abandoned signals that would “cross-talk” amidst neighbouring wires on the 40-conductor cable are “absorbed” by these additional ground wires, recuperating signal reliability. The added ground wires can equate to all of the even-numbered wires, or all of the odd-numbered wires within the cable.
Majority of wires within an IDE Cable are used to transmit data connecting the motherboard and the drives. Now-a-days Enhanced Integrated Device or Drive (EIDE) has become a common standard because it four times faster than its counterpart the IDE standard.
It was the American National Standards Institute (ANSI) who adopted IDE as a standard in the year 1990. ANSI calls IDE as Advanced Technology Attachment (ATA). Today almost all the new computers have an inbuilt IDE controller into the motherboard. But with the advancement of technology, slowly and steadily Serial Advanced Technology Attachment (SATA cables) are being used for connecting hard drives or CD drives to motherboards. This new invention, which is smaller in width, helps in relocating data at a fast pace as compared to the older IDE cables and is slowly replacing the older IDE Ribbon cable I.e. PATA. The data transfer rate of SATA cables starts from 1.5Gbits.
Buying tips: IDE Cables
• Check whether the IDE cables allow custom placement of the connectors on the cable and offer elasticity in the placement of IDE drives?
• Check whether the cable has 2A AC power supply to guarantee adequate power to meet the needs of the drives which are relatively power-consuming.
• If you intend to use 80-wire pinned cables, connect the blue end connector to the system board, gray middle connector to the Slave, and the black end connector to the Master for appropriate data transfer efficiency.

Can I cut open an extension cord and connect jumper cables from a car battery to the extension cord ?
I want to be able to plug something into the extension cord which will be connected to my car battery through a set of jumper cables.
As long as the extension cord is only connected to the car battery with the jumper cables you would only be able to operate a 12V "something". Normally, this is accomplished using the cigarette lighter with a proper adapter. Normally, this is a vacume cleaner, a small fan, or a phone charger. However, since you obviously plan to "plug" the device into the extension cord, I assume that is the type plug on it. Just remember the car is only producing 12 volts so if it is less than 12 volts or more than 12 volts it ain't gonna work.
Be careful if you do this. You need to make sure that jumper tongs don't touch one another--keep them insulated from an arc, especially since the 2 wires in the cord are very close to each other. If it "shorts" it will blow up your car battery and if you are standing near it it could hurt your ears from the explosion, or could splash acid on you from inside the battery when it explodes. Exploding batteries are not fun.
The other answerers think you are planning to plug the cord into the wall in an electrical outlet with 120V power, but they did not read what you said, like I did.
One has to wonder why you're doing this?
