Abstract
A hard disk drive enters a low power mode to reduce power consumption. To maintain communication with a host device, a communication interface remains energized along with a circuit portion storing configuration data for the communication interface. The hard disk drive may have a Universal Serial Bus (USB) interface to provide two-way communication to external data processing equipment. The hard disk drive may have a system on a chip (SoC) core to issue the low power mode entry command. During the low power mode, circuitry for external communication is kept in an active state.
