发明名称 Disk drive employing a disk command data structure for tracking a write verify status of a write command
摘要 A disk drive is disclosed comprising a disk having a plurality of tracks each comprising a plurality of data sectors for storing a plurality of data blocks. A microprocessor initializes a write verify counter in a disk command data structure and executes a write command. The microprocessor executes a write verify operation to verify the recoverability of the data written to a plurality of target data sectors. If the write verify operation fails for a target data sector, the microprocessor updates the write verify counter in the disk command data structure and re-executes the write command and the write verify operation. If the write verify operation fails a number of times such that the write verify counter exceeds a threshold, the microprocessor relocates a data block from the failing target data sector to a spare data sector.
