Trying to fix old laptop it had this hardrive installed originally: http://www.newegg.com/Product/Product.aspx?Item=N82E16822145092 THe hardrive stopped responding dianositics,spinrite, nothing would fix. So i purchased a new one for it here: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136129 Is there something I am missing why wont the computer detect the new hard drive?
