ABSTRACT:
In an external disk drive system comprising a disk drive, a bridge controller comprising a plurality of Bridge Controller Host (BCH) interfaces adapted to establish communication between the external disk drive system and an external device via a plurality of different communication mediums, a method for switching from a first BCH-interface communicating with the external device via a first communication medium to a second BCH-interface during the operation of the external disk drive system. The method comprising sensing a connecting of a second communication medium to the external disk drive system via the second BCH-interface; determining an interface priority of the second communication medium over an interface priority of the first communication medium; dismounting the disk drive from the first communication medium based on the determining; and mounting the disk drive to the second communication medium wherein the external disk drive system remains operational during the dismounting an mounting.
