40 Pins / 80 Wires

As ID transfer rates kept increasing, the limitations of the 40-pin cable became an issue. The solution was to add a ground wire between each signal carrying line on the 40-pin cable. This extra ground wire absorbs crosstalk. Crosstalk is any stray signal that 'leaks' from the original wire. Pin 34 on the motherboard side can determine if the 80-conductor cable is present.

[spacer]Standardization Comes to IDE Cable (Finally)

Another feature of this new cable is color-coding the connectors. The new coding scheme is as follows:

Blue: This connector is attached to the motherboard (or host adaptor).

Gray: This accepts the secondary drive (if it exists).

Black: This accepts the first (or only) drive.

The color-coding came about because if a single drive was placed in the middle of the cable, it could cause signal issues. Before, this was considered not advisable. Now it is flat out illegal.
