  • Method and device to update data transfer count for disc drive
    Patent number: 6470063
    Abstract: Method and device to update a data count in a data transfer operation in which a data counter generates an intermediate count value in accordance with a first amount of data to be transferred to a storage media; and an augmenter augments the intermediate count value by a specified count value in accordance with data to be transferred to the storage media in addition to the first amount of data, wherein the updated count value is loaded into the data counter such that the intermediate count value becomes equal to the updated count value during the data transfer operation.
