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.
