Page 0C (Notch Parameters) The notch page contains parameters for variable number of blocks per cylinder. Each section of the logical unit with a different number of blocks per cylinder is referred as a notch. The only field that is changeable is Active Notch field. ! ND of one means that the drive is a notched drive. ! LPN of zero means that the notches are based upon physical parameters of the drive (cylinder #), not logical parameters. ! Maximum Number of Notches is the number of notches the drive can support. ! Active Notch indicates to which notch subsequent MODE SELECT/SENSE command parameters pertain. A value of 0 is used for parameter values which apply to all notches. Values from 1 to the maximum value depending on the model specify the notch number, where notch 1 is the outermost notch. The following mode parameters are based on the current active notch: Mode Page 2 - Read Buffer Full Ratio - Write Buffer Empty Ratio Ultrastar 146Z10 hard disk drive specifications 102
