摘要： A system, method and data storage device for encrypting data to provide at-rest data encryption of data in the data storage device. The system includes a compression engine for receiving a host data stream packet and selectively generating a compressed data packet, and an encryption engine in electronic communication with the compression engine for receiving an unencrypted data packet from the compression engine. The unencrypted data packet comprises the compressed data packet when the compression engine generates the compressed data packet. The unencrypted data packet comprises the host data packet when the compression engine does not generate the compressed data packet. The encryption engine generates an encrypted data packet having an encrypted component corresponding to the unencrypted data packet and a set of meta data indicative of one or more characteristic of the encrypted data packet.

摘要： A data encryption system with encryption integrity verification includes an encryption engine configured to receive an unencrypted data packet and generate an encrypted data packet based at least in part on the unencrypted data packet. The system also includes a decryption engine in electronic communication with the encryption engine, the decryption engine configured to receive the encrypted data packet and generate a decrypted data packet based at least in part on the encrypted data packet. The system further includes a comparator in electronic communication with the encryption engine and the decryption engine, the comparator configured to receive the unencrypted and decrypted data packets, determine whether the unencrypted and decrypted data packets are identical, and present the encrypted data packet as an output when the unencrypted and decrypted data packets are identical.
摘要翻译：具有加密完整性验证的数据加密系统包括被配置为接收未加密数据分组并至少部分地基于未加密的数据分组生成加密数据分组的加密引擎。所述系统还包括与所述加密引擎进行电子通信的解密引擎，所述解密引擎被配置为接收所述加密的数据分组，并且至少部分地基于所述加密的数据分组来生成解密的数据分组。该系统还包括与加密引擎和解密引擎进行电子通信的比较器，比较器被配置为接收未加密和解密的数据分组，确定未加密和解密的数据分组是否相同，并将加密的数据分组作为输出当未加密和解密的数据分组是相同的。

摘要： A system for recording the history associated with writing data onto rewriteable media includes an access head for writing data onto the media and reading data from the media. A drive motor moves the media past the access head. A write formatter formats data into a device block to be written onto the media. A read formatter detects errors in data read from the media. A control unit determines an error recovery procedure based on an error detected in reading the media and enables the write formatter to insert an indication of the error recovery procedure into the device block. The error recovery procedure is then attempted. The process is repeated until either a successful write occurs or the media is determined to be bad.
