Please write clearly...your post is hard to understand. And if you want to know what the meaning of these options are, read the man page for the hdparm command. It explains everything, as would a quick Google search.

deepak;

For the most part, you appear to be ignoring comments from me and others as to how best to interact with this site. In most of your threads, you have not posted any follow-up when people offered advice, suggested where you could look, or simply asked you for some clarification. You also have not responded to my e-mail on this.

This is now a formal warning: Please do not continue posting random questions without any follow-up---especially when you don't show evidence of having done the simple Google searches.

Thanks...was kinda worried when I saw it, then confused. :)
