MODE 0~4 reflects the HDD data transfer rate. The higher the MODE
value is, the better is the HDD data transfer rate. But it does not mean that
you can select the highest MODE value just as you like, you first have to
be sure that your HDD supports this MODE, otherwise the hard disk will
not be able to operate normally.
