     of the system. Make sure to learn the proper use of each setting
     and the common pitfalls in configuration.  The man pages for the
	hdparm command can be
     very instructive for learning more about this.  You can view these man
     pages by clicking on the link above or by typing man
     hdparm at a shell prompt.
