I got a new hard drive. It is a Western Digital Caviar SE16 500GB Hard Drive - 7200, 16MB, SATA-300, OEM. I am trying to use it as a secondary HD. My first one is ata. When I plug the new hard drive in I plug it in to the group of sata ports that my cd drive is pluged into. Well when I boot the computer it gets to the first screen. Press delete for BIOS or TAB or what ever. At that screen i hit delete and it dosnt work. I think it freezes. If i hit tab it goes to a screen to a different screen, but i cant enter BIOS. It wont load windows off my main hard drive. I cant even tell if it is reading it.
