Powerbook is not recognizing my new hard drive replacement

Hi, My old 80GB hard drive that came with my 15" 1.5ghz powerbook died last week, under S.M.A.R.T it says failing, get clicking noises and all that good stuff. So I bought a Western Digital model beve2500 250gb hard drive to replace it, it's a comatable drive eide/pata. But it's not showing up in the disk utility, or systems profile. It's connected and I can here the HD spinning but it does not show up anywhere. I even reconnected the broken hard drive and it shows, is there something I'm missing or is the drive busted?

Thanks in advance.
