Abstract: A stand-alone digital media player is provided in connection with a removable media storage device which includes an audio panel (start/stop, forward, reverse, eject buttons), audio control circuitry, audio output and power source. The removable media storage device may be used as an internal/external storage device and as a digital media player by virtue of audio playback functionality added to the removable media storage device and/or a portable adapter housing coupled to the removable media storage device. Where the power source is a rechargeable batter included in the removable media storage device, the battery will recharge when attached to the portable computer when running on AC Power and provide additional backup power to the portable computer when needed.
