A hot swap circuit board and associated cable and connector arrangement for an ATA100 computer-disk drive interface is disclosed. The hot swap circuit board comprises a key-switched power supply control circuit with a simultaneously key-operated mechanical lock, a logic control circuit for READ and WRITE control signals and a set of logic switchable bi-directional impedance circuits with signal regeneration for the control and data signals across the ATA100 Interface. During normal operation, a security lock on the hot swap circuit board is kept in its locked position thus preventing any accidental disconnection of the ATA100 interface connector while simultaneously supplying electrical power and transmitted and regenerated control and data signals across the ATA100 interface. The unlocking mechanism is also disclosed.
