摘要： Method and apparatus for transferring data between a host device and a data storage device having a first memory space and a second memory space. The host issues access commands to store and retrieve data. The device stores commands in the first memory space pending transfer to the second memory space. An interface circuit evaluates relative proximity of first and second sets of LBAs associated with pending first and second commands, and delays promotion of later pending commands in front of earlier pending commands during an overlap condition. If the overlap is caused by performance enhancing features (PEF) the PEFs are disabled so the commands can be scheduled for disc access. Indicators are set in the commands to signal that a PEF has caused the overlap and that PEF can be disabled. Values are added to indicators in the commands such that the PEFs can be modified and avoid overlaps.

摘要： The application relates to defect management using mutable logical to physical association. Embodiments disclosed utilize mutable mapping between logical blocks and physical blocks. Dynamically updated mapping data, which mutably associates the logical blocks and the physical blocks, also includes physical block defect allocations.

摘要： Method and apparatus for transferring data between a host device and a data storage device having a first memory space (such as a buffer) and a second memory space (such as magnetic discs). Data are stored on the discs in host-addressable data sectors. The data storage device is configured to operate in a local mode of operation and a nonlocal mode of operation. During the local mode, nonrequested user data are retrieved from the discs and placed into the buffer in anticipation of a future request for the nonrequested user data. During nonlocal mode, such nonrequested user data are not retrieved. An interface circuit monitors host data access patterns and dynamically switches between the nonlocal and local modes in relation to proximity of a data sector address of each most recently received read command to data sector addresses associated with previously received read commands.
