Abstract: For securing content accessed from storage device, the storage device is associated with a licensee identifier. The licensee identifier is provided as input to an algorithm that generates, based on the identifier, a determinate set of instructions for a computer, for example, source code in a coding language, compiled binary code, or pseudo code that is capable of being translated into source code. The code, once compiled to machine-usable form, can be executed by a processor to perform a permutation operation that is unique to the licensee identifier. The output of the permutation operation can be used for protecting data provided by the storage device.

Abstract: A method and system are disclosed that permit a host application to obtain cluster location data, for example logical addresses associated with the clusters of a file, and to allow a host application to communicate the logical block address mapping information to firmware of a storage device. The method includes the host transmitting one or more clusters or partial clusters having a signature to the storage device where the storage device knows or has been instructed by the host to look for the signature. The storage device may receive clusters having a signature and, responsive to a host request, return logical address information to a host for the location in the storage device of the marked clusters. The host may parse a data structure on the storage device to obtain remaining cluster location information using a file's first cluster location or may request that the storage device return the cluster location information.

Abstract: A method and apparatus for facilitating the upgrade of device drivers for computer peripheral devices includes detecting a version of the device driver in use by the computer from data sent by the computer to the peripheral device determining whether the version of the device driver may be out of date signaling the computer if it is determined that a newer version of the device driver may be available.
