摘要： A disk drive and a control method thereof to reduce the number of write operations to a medium while minimizing command overhead time. A disk drive 10 comprises a hard disk controller (HDC) 13, a cache memory 14, and a host interface controller (HIC) 15 with a command queue for retaining a plurality of commands which are cached in cache memory 14. The HIC 15 performs the periphery interface processing by hardware. The disk drive 10 further comprises a local microprocessor unit (MPU) 16 for controlling the overall operation of HDD 10, including operations of HDC 13 and HIC 15. The local MPU 16 instructs the HIC 15 to write data to a medium by write commands cached in the cache memory 14. When local MPU 16 retrieves a command from a plurality of write commands cached in cache memory 14 which is completely overwritten by a command more recently issued, a write operation to the medium is not performed by the retrieved command.

摘要： Methods and apparatus are described for a data transfer unit between a storage unit and a host, wherein a slower data transfer rate is established when a predetermined error is detected. In one embodiment the cyclicity of the error occurrence calculated and a wait is inserted between data to avoid transferring data at the calculated cyclicity point of the detected error. Optionally the data transfer unit may return the data transfer rate to the original data transfer rate or state after a predetermined time has elapsed, after a predetermined number of commands have been received, after a predetermined amount of data have been transferred, or by combination of these.

摘要： An error recovery procedure (ERP) in a storage device such as a rotating magnetic hard disk drive is executed to the last step regardless of the established time-out period for an instruction, thereby more reliably recovering from errors. In accordance with one embodiment of the invention, when a disk drive receives a reset instruction from a host during the execution of an ERP, it executes the ERP until the error is recovered, or to the last step without interrupting the ERP. Further, in accordance with another embodiment of the invention, when a disk drive receives a reset instruction during the execution of an ERP, it stops execution of the ERP and holds the number K of the step which was completed immediately before stopping, and when receiving a retry instruction after that, sequentially executes the ERP from the K+1-th error recovery step.

摘要： Data difficult to be written to a target sector (write) of a hard disk is recorded to a MRAM. The target sector (write) to which the write has been difficult is checked in a background of performing data write to the next target sector (write). When there is no error, the data stored in the MRAM is written to the target sector (write) of the hard disk. When there is any error, the data stored in the MRAM is written to an alternative sector of the hard disk. Data difficult to be read from a target sector (read) of the hard disk is recorded to the MRAM. The target sector (read) from which the read has been difficult is checked in a background of performing data read from the next target sector (read). When there is any error, the data stored in the MRAM is written to an alternative sector of the hard disk.

摘要： A method and an apparatus for predicting the recovery time required until the hard disk drive is restored to a usable state from a stand-by state. The recovery time is a time required until the hard disk drive is restored to a usable state from the stand-by state. Then, the predicted recovery time is reported to the host system. When the host system knows how much time is needed until the disk drive is recovered, it can schedule a task to be completed before the hard disk drive is restarted, thereby scheduling of all the tasks in the host system can be optimized.

摘要： The signal output device of the present invention comprises of a driver circuit and a controller. The signal sending method of the present invention sets any one of a plurality of the different sending rates. The method also includes setting a slew rate of the driver circuit to a standard value that is in accordance with the predetermined data transfer rate, thereby starting signal transmission. The next step involves determining whether or not a data transfer error occurrence rate is below a predetermined allowable threshold. Then, changes in the slew rate of the driver circuit are made if the data transfer error occurrence rate is determined to be over the allowable threshold. Next, a search for a slew rate value that can decrease the data transfer error occurrence rate below the allowable threshold or decrease the data transfer error occurrence rate is performed. The new slew rate value is set as a new standard value. Finally, the process ends by setting the new standard slew rate for the driver circuit if the slew rate value can decrease the data transfer error occurrence rate below the allowable threshold or decrease the data transfer error occurrence rate.
