I went to my local computer shop and asked did they have an ide cable with a 40 pin connection with 80 wire. They said i saw looking for a ATA 133 IDE Cable does this seen right to everyone?
 
40-Pin IDE is what you use for a Hard Drive or CD Drive, so yes a 40-Pin connector is an ATA 133 IDE Cable. A Floppy cable is 24-pin. Although im not sure what you mean by "with 80 wire".
 
corretc me if im wrong but a standard ide cable has a 40 pin connection and 40 wires coming out from the connection to transfer data! but what im looking for is a 40 block connection with 80 wires speeding the transfer rate of data!
 
I think your mistaking, i've never seen a drive or motherboard that can accept 80pins. And i've never seen a cable with 80 wires, i dont know how that would even speed up the transfer since it originates from only 40 wires.

But if you find something that does have 80 wires, please post cause i'd really like to see that.
 
yeh, they do exist, although about as rare as a pink polar bear. It has 40 pins but has 2 wires connected to each pin, so forth doubling theoretical data throughput rates. It doesnt quite double them but it does do a lot for data rates. You computer shop doesnt know what they are talking about, people in a business should know things like this exist but are hard to get, dumbasses.... think they can run a business with in-adequate knowledge.... pft...

well he was the one who told me I need a ATA 133 cable which seems to be right no one has actual answered my question off is it the right cable. Although dragon you are kinda right about not knowing much about computers ther is man who does all the repairs at the back of the shop who knows what he is on about but at the front is two old grannies who havent got the first clue but deal with the customers!

You sure is an 80 wire one, they are rare. and not ususally bundled with anything, they are aftermarket stuff.

80 wire Ultra DMA cables are really common. most computers use them for the harddrive for higher data transfer rates. a really common mod for the xbox is to upgrade the harddrive cable.

Pink Polar bears must be really common!

What your looking for is a Ultra DMA (80-Conductor) IDE/ATA Cables

Actually, IIRC, the in-between wires are there for shielding purposes-- reduced crosstalk allows higher transfer rate.

actually, the extra wire allows more efficent use of the clock speed, data can be trasfered twice perclock, insted of once. hence doubling the speed.

:confused: ... and how is it supposed to do that? The connector is still only 40 pins.

Yale has this to say:

The first generation of DMA transferred data at a 33 MHz rate and did not require a change to the disk cable. However, to transfer data at any higher speed, the old grey cable with 40 wires was not good enough. A wire is also an antenna. When two wires run next to each other for a distance, as in the ATA cable, The electric activity on one wire generates an electromagnetic signal over the length of the wire, This is then picked up by the wire next to it and produces a weak duplicate of the original activity. At high speed this "crosstalk" becomes a problem. The solution is to transmit the data over twisted pairs of wires, but this would require a complete reengineering of the ATA interface.

Fortunately, the crosstalk was so weak that a less complicated solution was possible. Although the ATA plug continued to have 40 pins, a new generation of "blue" ATA cables now has 80 wires. Every other wire is a dummy, it carries no signal and is connected to ground. By this trick, between every two "adjacent" signal carrying wires there is one dummy wire to receive and dissipate the electromagnetic crosstalk. This is sufficient to bump the Ultra DMA transfer up to 100 or 133 MHz.

To go higher than 133 MHz, you need an entirely different technology. Serial ATA transfers data over a much smaller cable using serial transmission of bits at a much higher clock rate. Currently, SATA transfers data at 150 Megabytes per second and a second generation 300 Megabyte per second version should be available shortly. Even 150 megabytes is more than twice the transfer speed of the fastest hard disk.

Techexams concurs:

The extra 40 strands in an 80-wire cable act as insulators between the 40 signaling strands to prevent crosstalk.
