摘要： A disk drive that includes nonvolatile memory for use when the disk drive is in standby mode also uses the nonvolatile memory, together with a volatile memory, as a cache when the disk drive is in both standby and non-standby mode. Each of the data blocks stored on the disks is also stored in a cache line of either the volatile memory or the nonvolatile memory. Each cache line in both the volatile and nonvolatile memory stores one or more data blocks and an associated tag. The tag contains at least a portion of the logical block address that corresponds to the data block that is stored in the cache line. The volatile memory also has locations allocated to store tags that “shadow” the tags in the nonvolatile memory. By searching the shadow tags in the faster volatile memory, it can be determined if a data block is in the nonvolatile memory without searching the slower nonvolatile memory.
摘要翻译：当磁盘驱动器处于待机模式时，包含用于磁盘驱动器处于待机模式的非易失性存储器的磁盘驱动器也将非易失性存储器与易失性存储器一起用作高速缓存。存储在磁盘上的每个数据块也存储在易失性存储器或非易失性存储器的高速缓存行中。易失性和非易失性存储器中的每个高速缓存线存储一个或多个数据块和相关联的标签。标签包含对应于存储在高速缓存行中的数据块的逻辑块地址的至少一部分。易失性存储器还具有分配用于存储“阴影”非易失性存储器中的标签的标签的位置。通过在快速易失性存储器中搜索阴影标签，可以确定数据块是否在非易失性存储器中，而不需要搜索较慢的非易失性存储器。

摘要： A method and system intelligent bit recovery is provided. The intelligent bit recovery determines which bits are toggling, and examines a subset of the potential bit patterns to determine which in the subset of potential bit patterns is valid. The subset is a fraction of the potential bit patterns, and is based on an understanding of the flash memory and the problems that may cause the toggling bits. The intelligent bit recovery may analyze at least one aspect of the flash memory to identify which problem is potentially causing the toggling bits, and to select the subset of potential bit patterns as solutions for the determined problem. Or, the intelligent bit recovery selects potential bit patterns for multiple potential problems. In either way, the subset of potential bit patterns examined by the intelligent bit recovery is a small fraction of the entire set of potential bit patterns.

摘要： A method and system for intelligent bit recovery identifies toggling bits, which change in value from one read to the next, and examines a subset of potential bit patterns. The subset is a fraction of the potential bit patterns, and is based on an understanding of the flash memory and the problems that may cause the toggling bits. The intelligent bit recovery may analyze at least one aspect of the flash memory to identify a problem, or plurality of problems, that is potentially causing the toggling bits, and to select the subset of potential bit patterns as potential solutions. The subset of potential bit patterns examined by the intelligent bit recovery is a small fraction of the entire set of potential bit patterns.

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： A data storage device comprises virtual storage devices that are each assigned to a subset of data sectors in a non-volatile memory of the data storage device. The data storage device receives configuration metadata for configuring each of the virtual storage devices from a host operating system. The configuration metadata is received in a standard format that is file system independent. The configuration metadata comprises a range of logical block addresses and a virtual storage device number assigned to each of the virtual storage devices. Each of the virtual storage device numbers is a unique identifier used by the data storage device to differentiate between the virtual storage devices. The data storage device uses the virtual storage device numbers and logical block addresses to identify data sectors in the virtual storage devices that are accessible by virtual machine operating systems.
