Figure 4.4 MODE SELECT parameters: drive parameters

Note:

When transfer of this page is requested by the MODE SENSE or MODE SENSE EXTENDED command, the IDD reports X '16' as the page length. However, in the MODE SELECT and MODE SELECT EXTENDED commands, if either X '16,' X '12' or X '0A' is specified, it is treated as if the IDD has specified the correct page length. The X '12' and X '0A' page lengths have been included in consideration of compatibility with previous models, but it is recommended that the INIT use the X '16' page length to support expanded specifications in the future.
