Title: Method and system for determining the data layout geometry of a disk drive

Abstract: A system and method for determining the disk drive parameters of any disk drive that may be encountered. A novel access pattern is applied to the disk drive and a novel technique used to interpret the measured results. In order to determine a data layout geometry of a disk drive, a plurality of sectors on the disk drive are accessed in sequentially decreasing order, starting from an initial sector. A completion time for each access is measured and parameters related to the data layout geometry of the disk drive are determined based on the measured access times. In order to determine the layout geometry, sectors immediately preceding track and cylinder skews are identified and a number of sectors per track and a number of tracks per cylinder are determined based on the identified sectors.
