1. An apparatus for dual porting a serial disk drive, comprising:

  • a first idle regenerator connected to a first serial master device, the first idle regenerator being capable of receiving and transmitting signals to the first serial master device including an idle character stream;

    a second idle regenerator connected to a second serial master device, the second idle regenerator being capable of receiving and transmitting signals to the second serial master device including an idle character stream;

    a third idle regenerator connected to the serial disk drive and the first and second idle regenerators, wherein the third idle regenerator is capable of communicating with the serial disk drive and the first and second idle regenerators; and

    a synchronization logic capable of synchronizing data transfers between one of the first idle regenerator and the second idle regenerator, and the third idle generator, wherein the synchronization logic is connected to the first, the second and the third idle regenerators.
