I have a PATA running right now with Win XP. I plan to use this drive as my backup. Will a Wd 120 Sata need any extra drivers or is this a plug and install Windows situation? Will My Mobo just accept it or will I need to go into the bios? Should I set up in the bios before I take out the old drive to boot from disk? When im ready to delete the old drive, all I need to do is right click it and click format? Will having two Windows drives cause a problem? I may have more questions but whoever answers these thank you very much.
