摘要： The invention is a storage device which implements a write barrier command and provides means for a host to designate other write commands as being sensitive or insensitive to the existence of write barrier commands. The device can optimize the execution of commands by changing the order of execution of write commands that are insensitive to write barrier command. In an embodiment of the invention a flag associated with the write command indicates whether the command is sensitive or insensitive to the existence of write barrier commands. In an embodiment of the invention the write barrier command can be implemented as a write command with a flag that indicates whether the command is a write barrier command. In one embodiment of the invention the queue of commands and data to be written to the media is stored in a non-volatile cache.

摘要： A verifiable security mode is provided for securing data on a storage device, such as a hard disk drive. When the verifiable security mode is enabled, only authenticated accesses to data stored on the storage device are permitted after entering a password. An end user is prevented from disabling the verifiable security mode. The verifiable security mode can be set to allow or disallow an administrator from disabling the verifiable security mode. The verifiable security mode can be implemented, for example, in firmware on a hard disk drive (HDD).

摘要： Enhancements to the functionality of a file system are provided. A file system can provide an additional level of error correction, in addition to the error correction provided by a data storage device. An extension to the metadata area in a file system can store index information about data files that the file system can use to reduce the time it takes to access the files. A file system can use extended metadata to store conditional access information for data files stored in the file system. A data storage device can also examine and characterize the data being stored in order to categorize a user's files automatically. Modules can be loaded into a file system to provide new functionality to the file system. The modules can load additional modules to extend their functionality.
摘要翻译：提供对文件系统的功能的增强。除了由数据存储装置提供的纠错之外，文件系统还可以提供额外的纠错级别。文件系统中的元数据区域的扩展可以存储关于文件系统可以使用的数据文件的索引信息，以减少访问文件所需的时间。文件系统可以使用扩展元数据来存储文件系统中存储的数据文件的条件访问信息。数据存储设备还可以检查和表征正在存储的数据，以便自动对用户文件进行分类。模块可以加载到文件系统中，为文件系统提供新的功能。这些模块可以加载其他模块以扩展其功能。

摘要： A storage system according to the invention maintains an arithmetic signature or fingerprint generated using the content of selected units of data stored on the media. The signature is stored in metadata in non-volatile storage on the system's electronics card preferably in a tamper resistant module (TRM). When reading a data unit from storage, the system uses the saved signature to verify that the data unit has not been altered by unauthorized means after it was stored. The content of the stored data is thereby bound to the metadata stored in the system's non-volatile storage so that by-passing or physically separating the bulk storage media (e.g. disks) from the system's electronics will not allow alteration of the data without detection. The method also prevents unauthorized data roll-back because the signature of old data will not match the current signature in the metadata.
摘要翻译：根据本发明的存储系统维护使用存储在介质上的所选择的数据单元的内容生成的算术签名或指纹。签名被存储在系统的电子卡上的非易失性存储器中的元数据中，优选地在防篡改模块（TRM）中。当从存储器读取数据单元时，系统使用保存的签名来验证数据单元在存储之后未被未经授权的方式更改。因此，所存储的数据的内容被绑定到存储在系统的非易失性存储器中的元数据，使得大容量存储介质（例如盘）与系统的电子设备的旁路或物理分离将不允许在没有检测的情况下改变数据。该方法还可以防止未经授权的数据回滚，因为旧数据的签名将不会与元数据中的当前签名相匹配。

摘要： A method is described for allowing disk drives, such as shingle-written magnetic recording (SMR) drives, to be shipped for customer use with portions of the magnetic media being left untested. The testing is then completed by the drive self-testing in the field. The drive is made functional at the factory by fully testing at least one operational set of regions including an I-region, an E-region and a write cache region. The operational set of regions works as a separate self-contained virtual disk drive and can be used immediately. The remaining untested areas on the media can be tested in the field by a background task and/or when the first write command is received that requires a new track or operational set of regions (on-the fly testing).

摘要： Digital watermark data is embedded into compressed media content that is transmarked when the compressed media content is converted to an analog format or into an uncompressed digital format. The watermark data uniquely identifies the converter/player device/user that converted the watermark-protected digital media content into the analog format or the uncompressed digital format. The presented media content in the analog format or the uncompressed digital format is modified as a function of the watermark data and the digital signature obtained from the converter/player device/user. The modifications are visible and essentially produce a correspondingly different media presentation for each converter/player device/user. The modifications, however, are selected so that they are nonessential to the storyline and, consequently, not noticed by a casual user.

摘要： This invention is a Viterbi algorithm combined with the use of error filters outputs to produce bit reliabilities. The present invention is a SOVA-like method using error filters to reduce the complexity of bit reliability determination further than that of the ordinary SOVA method. Error patterns corresponding to each of a handful of dominant i.e., most common error patterns are determined from experimental data. Error filters determine likelihoods of each postulated error pattern. These likelihoods are then combined to produce bit reliabilities that may be passed on to an outer error correction decoder. The filters, typically six or seven of them, resolve most of the errors thereby simplifying computation dramatically.
