I think asivakumar is suggesting you modify your BIOS settings, but I'm not sure how he is able to provide this info since you have not mentioned ANYTHING that would give a clue regarding your computer or its BIOS.  (You haven't done anything wrong Iwishiknew.)

asivakumar, you seem to be jumping the gun here.  How do you know if this computer even has SATA?
