摘要： A disk drive is disclosed including a disk, and a head actuated over the disk. Control circuitry within the disk drive is operable to receive a write operation for a refresh zone of the disk, measure a write operation quality parameter that affects the quality of the write operation, and perform the write operation. An update function is enabled in connection with performing the write operation, wherein the update function is operable to update a refresh monitor as a function of the write operation and the write operation quality parameter. Data stored in the refresh zone of the disk is refreshed in response to the refresh monitor.

摘要： A disk drive is disclosed including a disk comprising a plurality of refresh zones, and a head actuated over the disk. The disk drive further comprises control circuitry for receiving access commands from a host. The control circuitry refreshes a refresh zone in a plurality of segments with an interval between each segment, and processes at least one of the access commands during the interval between at least two of the segments, wherein a size of each segment and the interval ensures an average throughput of access commands received from the host does not fall below a first threshold.

摘要： A disk drive and method are disclosed for data transfer initiated by nonstandard disk-drive commands on a serial interface that only supports standard disk-drive commands. In the method, a nonstandard disk-drive command for data transfer is embedded within a first data block accessible using a first standard disk-drive command. The first standard disk-drive command is transmitted through the serial interface causing the first data block to be transferred from the host computer to the disk control system. The embedded command is extracted from the transferred first data block and provided to the disk control system. A status response is transmitted to the host computer based on the extracted command. At least one additional standard disk-drive command is transmitted through the serial interface to the disk control system for transferring the identified data between the host computer and the disk drive.

摘要： A disk drive is disclosed comprising a disk, a head, and an actuator for actuating the head radially over the disk. The disk comprises a plurality of tracks, each track comprises a plurality of data sectors for storing data and a plurality of sector-reconstruction-interleave (SRI) sectors for storing redundancy data. The redundancy data stored in a selected one of the SRI sectors is generated in response to the data stored in an interleave of the data sectors corresponding to the selected one of the SRI sectors.

摘要： A disk drive is disclosed comprising a head actuated over a disk. A redundancy generator generates a plurality of redundancy symbols appended to user data to form a codeword C(x) written to a selected data sector on the disk. During a read operation, a syndrome generator generates a plurality of error syndromes in response to a received codeword C′(x) generated by reading the selected data sector. An error detector, responsive to the error syndromes, detects a number of errors in the received codeword C′(x), and a plurality of counters count a number of times the number of errors falls within a predetermined plurality of ranges to thereby provide a distribution of the errors. The error distribution is used, for example, for selecting a track density or ECC depth, or for failure prediction or defect mapping.

摘要： An information storage device is disclosed (such as a disk drive) comprising an interface for connecting to a host through a cable, and control circuitry for communicating with the host over the cable by executing a communication process. The communication processes comprises the steps of transmitting a communication request to the host over the cable and waiting to receive a response from the host over the cable. A cable loss event is logged if the host fails to respond after executing the communication process at least twice. Performing the communication process multiple times before logging a cable loss event helps ensure a communication failure is actually due to a faulty cable connection.

摘要： A disk drive is disclosed comprising a disk for storing initial host requested (IHR) data requested by a host computer during a start-up process of the host computer, a head actuated radially over the disk, and a non-volatile semiconductor memory (NVSM) for caching at least part of the IHR data. The disk drive transmits the cached IHR data from the NVSM to the host computer during the start-up process thereby avoiding the delay associated with initializing the mechanics of the disk drive as well as conserving battery power for mobile applications.
