When the drive is shipped from the factory, there are not parameter page “Save” values except for Page 3 (Format Parameters) and Page 4 (Drive Parameters). “Save” values for the parameter pages specified in the MODE SELECT command are generated for the first time when that command is executed with “1” specified in the “SP” bit.

Figure 4.1 MODE SELECT parameter structure

The MODE SELECT parameters include parameters which can be changed by the INIT as desired, parameters which the INIT cannot change, which whose values are determined by the HDD unilaterally and parameters which can be changed by the INIT within certain appropriate limits. The HDD also contains parameter fields which are applicable for rounding processing ("rounding up" or "rounding down") of parameter values specified by the INIT to values which the HDD can use in actual operation.

When changing of parameters other than "variable parameters" is requested by the INIT in the MODE SELECT parameters which it transfers in this command, or when changes which are outside the permissible range are requested, even though they are "variable parameters," this command is terminated with a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in parameter list [=26-00]) and all the parameters specified by the INIT are disabled. Furthermore, parameter fields exist which ignore the values specified by the INIT, even if the parameters are "variable parameters." Details are explained in the description of each page descriptor in this item.
