摘要： An intelligent write command routine improves the operational efficiency of a data storage device (DSD) by avoiding media access of the disk when a logical block address (LBA) and the physical sector are unaligned, thus reducing write time. When a write command is received by the DSD from the host, the intelligent write command routine maintains the read data of the read buffer, instead of clearing the read buffer and performing a read of the target sector on the disk per standard protocol. The intelligent write command copies the necessary adjacent sector data from the read buffer as a data patch to the write buffer to splice around the write data received with the write command. Following each write command, the data written to the disk in the write buffer is copied to the read buffer. The read buffer is maintained with the most current data on the disk and does not need to be flushed unless the LBA of the write command is beyond the data ranges stored in the read buffer.
摘要翻译：智能写命令例程通过在逻辑块地址（LBA）和物理扇区未对齐时避免磁盘的介质访问来提高数据存储设备（DSD）的操作效率，从而减少写入时间。当DSD从主机接收到写入命令时，智能写入命令例程维护读取缓冲器的读取数据，而不是清除读取缓冲区，并根据标准协议对磁盘上的目标扇区进行读取。智能写入命令将读取缓冲器中必要的相邻扇区数据作为数据补丁复制到写入缓冲区，以便使用write命令接收的写入数据进行拼接。在每个写命令之后，写入缓冲区中的磁盘的数据被复制到读缓冲区。读取缓冲区用磁盘上最新的数据进行维护，除非写入命令的LBA超出存储在读取缓冲区中的数据范围，否则不需要刷新读取缓冲区。

摘要： A method and apparatus for receiving data at a non-solid state storage device, which includes a store cache and a storage medium. The received data is written to the store cache and transferred from the store cache to the storage medium. In response to receiving a signal at the storage device that is indicative of a power off condition of a data source device from which the data was received, at least a portion of the data remaining in the store cache is transferred to the storage medium prior to powering off the storage device.

摘要： In one illustrative example, a bridge connecting a universal serial bus (USB) interface and an advanced technology attachment (ATA) interface may decode a customized small computer system interface (SCSI) command to enable the system to send ATA commands over the USB interface. A customized SCSI command may implement a “pass-through” feature that allows the system to support logical block addresses (LBA) of 48 or more bits, and Self-Monitoring and Reporting Technology (SMART) commands associated with a hard disc drive (HDD). In conjunction with the bridge, the system may send an ATA-command payload, within a wrapper. The bridge may remove the wrapper without substantially altering the payload, and send the ATA-command payload over the ATA bus.
摘要翻译：在一个说明性示例中，连接通用串行总线（USB）接口和高级技术附件（ATA）接口的桥接器可以解码定制的小型计算机系统接口（SCSI）命令，以使系统能够通过USB接口发送ATA命令。定制的SCSI命令可以实现“传递”功能，允许系统支持48位或更多位的逻辑块地址（LBA），以及与硬盘驱动器（HDD）相关联的自我监视和报告技术（SMART）命令）。与桥接器一起，系统可以在包装器内发送ATA命令有效载荷。桥接器可以在不大幅改变有效载荷的情况下去除封装，并通过ATA总线发送ATA命令有效载荷。

摘要： An interlaced even and odd mapping maps between a logical address space and a physical address space. In one embodiment, an interlaced even and odd mapping scheme provides for converting between a target logical block address (LBA) and a target physical disc sector or cylinder head sector (CHS). In other embodiments, the mapping may be used in any application wherein address translation is desired between address spaces. For example, the mapping may be used to convert between a target logical address space and a target physical address space in a digital computer environment that includes a data storage device, such as a disc drive, for persistent storage. The interlaced even and odd mapping scheme allows for larger physical sector sizes on the data storage device than the logical sector sizes on a host computer.
摘要翻译：隔行偶数和奇数映射在逻辑地址空间和物理地址空间之间映射。在一个实施例中，隔行偶数和奇数映射方案提供在目标逻辑块地址（LBA）和目标物理盘扇区或气缸头扇区（CHS）之间的转换。在其他实施例中，映射可以用于在地址空间之间需要地址转换的任何应用中。例如，映射可以用于在数字计算机环境中的目标逻辑地址空间和目标物理地址空间之间进行转换，数字计算机环境包括用于持久存储的诸如盘驱动器的数据存储设备。隔行偶数和奇数映射方案允许在数据存储设备上比主计算机上的逻辑扇区大小更大的物理扇区大小。

摘要： A mapping table is modified to match one or more specified storage conditions of data stored in or expected to be stored in one or more logical block address ranges to physical addresses within a storage drive having performance characteristics that satisfy the specified storage conditions. For example, the performance characteristics may be a reliability of the physical location within the storage drive or a data throughput range of read/write operations. Existing data is moved and/or new data is written to physical addresses on the storage media possessing the performance characteristic(s), according to the mapping table. Further, a standard seeding or a seeding override for the re-mapped logical block addresses can prevent read operations from inadvertently reading incorrect physical addresses corresponding to the re-mapped logical block addresses.
摘要翻译：修改映射表以将存储在或预期存储在一个或多个逻辑块地址范围中的数据的一个或多个指定存储条件与具有满足指定存储条件的性能特性的存储驱动器内的物理地址相匹配。例如，性能特征可以是存储驱动器内的物理位置的可靠性或读/写操作的数据吞吐量范围。根据映射表，现有数据被移动和/或新数据被写入具有性能特征的存储介质上的物理地址。此外，用于重新映射的逻辑块地址的标准播种或播种覆盖可以防止读取操作无意中读取与重新映射的逻辑块地址相对应的不正确的物理地址。
