摘要： A disk drive is disclosed that is responsive to standard disk-drive commands associated with disk-drive operations and to nonstandard disk-drive commands required for disk drive manufacture and quality testing. The disk drive includes a disk, a head actuated radially over the disk, and a disk control system. The disk control system responds to disk-drive commands and accesses data storage locations on the disk through the head. A serial ATA interface couples the disk control system to a host computer. The serial ATA interface is configured to transfer standard disk-drive commands from the host computer to the disk control system and is configured to not transfer nonstandard disk-drive commands from the host computer to the disk control system. The extracting means extracts a nonstandard disk-drive command that is embedded within a data block accessed using a standard disk-drive command and provides the extracted nonstandard disk-drive command to the disk control system.

摘要： The present invention may be embodied in a method, implemented in a disk drive, for analyzing a magnetic media surface for indications of rough handling or “head slap.” In the method, a media surface is scanned to detect errors indicative of media defects. Location information is recorded for each detected error. Defect clusters are identified based on the location information. A confidence factor is generated based on a comparison between the defect clusters and a representation of the physical dimensions of the head. Whether the confidence factor indicates an impact between the head and the media surface is determined.

摘要： A disk drive is disclosed comprising a disk including a plurality of addressable locations containing stored data, and signal processing circuitry comprising reading means responsive to the stored data for producing a read signal, and means responsive to the read signal for producing decoded data that is subject to errors. A control system, responsive to the decoded data, computes an error rate measurement by performing a first data-recovery procedure conducted under conditions providing for increasing the probability of achieving a first successful data-recovery step, and by performing a second data-recovery procedure conducted under conditions providing for increasing the probability of achieving a second successful data-recovery step. The control system accumulates a first accumulated value representing occurrences of the first successful data recovery step and accumulates a second accumulated value representing occurrences of the second successful data recovery step. The control system weights the first accumulated value by a first weight to generate a first weighted value, and weights the second accumulated value by a second weight different than the first weight to generate a second weighted value. The control system computes the error rate measurement by combining the first and second accumulated values and the first and second weighted values.

摘要： A disk drive that includes a disk defining a multiplicity of sectors operates in accord with a method comprising the steps of providing a firmware-controlled state machine which can be in any of a plurality of states including an off-line in-progress state. While the state machine is in the off-line in progress state; a firmware-controlled scan of the multiplicity of sectors is performed. While performing the firmware-controlled scan, steps are performed to maintain a list of sector identifiers such that each sector identifier in the list points to a sector that has failed, preferably repeatedly, to provide valid data on the fly. While the state machine is not in the offline in-progress state; the drive responds to a request to write data at a specified sector by determining whether the specified sector matches a sector identifier in the list, and if so, autonomously performing a read-verify-after-write operation.

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.
