My old hard drive failed and so I went to Microcenter were they gave me a new hard drive a WD Scorpio Blue. I replaced the hard drive and put in the Snow Leopard install disk. I got to the screen where it says to select the disk I want to install on but nothing apears in the white box. I went on disk utlities and nothing but the Install Disk shows up there. I can't find anything to tell me how to fix this. Can someone help? By the way i have a 2 year old MacBook Pro 13".
