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 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.
摘要翻译：公开了一种信息存储装置（例如磁盘驱动器），其包括用于通过电缆连接到主机的接口，以及用于通过执行通信过程通过电缆与主机通信的控制电路。通信过程包括以下步骤：通过电缆向主机发送通信请求，并等待通过电缆从主机接收响应。如果主机在执行通信过程至少两次后无法响应，则会记录电缆丢失事件。在记录电缆丢失事件之前多次执行通信过程有助于确保通信故障实际上是由于电缆连接故障。

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.
