Drive Interface Connectors
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.
NOTICE: When you connect an IDE interface cable, do not place the colored stripe away from pin 1 of
the connector. Reversing the cable prevents the drive from operating and could damage the controller,
the drive, or both.
