2 interface cable
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other
connector. Keyed connectors ensure that the pin-1 wire in the cable goes to the pin-1 end of the connector. The pin-1 end of a connector on a board or a card
is usually indicated by a silk-screened "1" printed directly on the board or card.

Connecting and Disconnecting Drive Cables
When removing an IDE drive data cable, grasp the colored pull tab and pull until the connector detaches.
When connecting and disconnecting a serial ATA data cable, hold the cable by the black connector at each end.
Like IDE connectors, the serial ATA interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a
filled-in hole on the other connector.
