A storage device and method for using a virtual file in a public memory area to access a plurality of protected files in a private memory area are disclosed. In one embodiment, a storage device receives a request from a host for access to a virtual file in the public memory area, wherein the virtual file is associated with a plurality of protected files stored in the private memory area. The storage device responds to the request by selecting and providing the host with access to one of the plurality of protected files stored in the private memory area. The storage device receives an additional request from the host for access to the virtual file and responds to the additional request by selecting and providing the host with access to a different one of the plurality of protected files stored in the private memory area.

A system and method for protecting cached streamed data is disclosed. The method may include the steps of generating an encryption key from the streamed data itself, encrypting the streamed data stored in the storage device and requesting the portion of the streamed data from the content server again when later playback is desired so as to allow the content server to enforce access limitations or takedown policies relating to the streamed data. The method may also include procedures for handling key generation over reliable or unreliable protocols.

A storage device and method for storage device state recovery are provided. In one embodiment, a storage device commences an authentication process to authenticate a host device. The authentication process comprises a plurality of phases, and the storage device stores the state of the authentication process, wherein the state indicates the phase(s) of the authentication process that have been successfully completed. After a power loss, the storage device retrieves the state of the authentication process and resumes an operation with the host device without re-performing the phase(s) of the authentication process that have been completed.

A powerfully simple digital media player and methods for use therewith are disclosed. In one embodiment, a digital media player with a simplified user interface is disclosed that, like an FM radio, allows a user to easily select a category of digital media for playback. In another embodiment, to make the experience more FM-radio-like for a user, instead of charging the user for the digital audio files, digital media files can be distributed for free (or at a reduced charge) by playing advertisements before, during, or after the playback of a digital audio file. In yet another embodiment, an exemplary network infrastructure is provided. In another embodiment, a generic streaming content file interface is presented. Other embodiments are disclosed, and any of these embodiments can be used alone or in combination with one another.

A method and system for refreshing content in a storage device are disclosed. In one embodiment, a content replication system authenticates to each of a plurality of storage devices in parallel without creating a unique secure channel with each respective storage device. After authenticating to each of the plurality of storage devices, the content replication system is permitted to write content to, but not read content from, each of the plurality of storage devices. The content replication system then writes content to each of the plurality of storage devices in parallel.
