    Abstract: Apparatus and method for managing a media cache through the monitoring of operational vibration of a data storage device. In some embodiments, a non-volatile media cache of the data storage device is partitioned into at least first and second zones having different data recording characteristics. Input data are received for storage in a non-volatile main memory of the data storage device. An amount of operational vibration associated with the data storage device is measured. The input data are stored in a selected one of the first or second zones of the media cache prior to transfer to the main memory responsive to a comparison of the measured amount of operational vibration to a predetermined operational vibration threshold.

    Abstract: A method includes adding a key version tag to an encryption key store that stores encryption keys. The key version tag is inserted into a data stream. The data stream including the key version tag is written to media. The data in the data stream is erased by scrambling the encryption keys and incrementing the key version tag in the encryption store by a digit. The data stream is replaced with a replacement data pattern when the key version tag stored in the encryption store and the key version tag located in the data stream mismatch.

    Abstract: A data storage device includes first and second controllers that independently and simultaneously process data from a recording medium. The first and second controllers each have respective first and second buffer managers coupled to respective first and second buffer memories. The first and second buffer managers are coupled to each other via an inter-controller data bus. The first controller is configured to receive a contiguous memory request for a block data transfer client of the first controller. A first part of the request is fulfilled from the first buffer memory via the first buffer manager, and a second part of the request is fulfilled from the second buffer memory via the second buffer manager communicating with the first buffer manager via the inter-controller data bus.
