When a hard drive is connected via USB, Firewire, or any other external port, SMART monitoring and testing are not supported for it.
When the drive is installed internally, does Disk Utility see it?
Were you running the same version of Leopard on your previous hard drive in this machine?
Did you yank on the hard drive ribbon cable when you removed the old drive? If so, you could have damaged the cable. Try putting the old drive back in. If that still works, the cable is OK.
What does "no clicking is available" mean? Does the trackpad click when you press it, but nothing happens as a result? That would suggest a flawed OS installation. Can you not depress the trackpad enough to make it click? That would suggest a swollen battery, but it would behave the same with the older drive installed. Is tap-to-click activated? If so, does that work any better than pressing the trackpad to produce a physical click? How about trying an external USB mouse from any other computer? Can you click with that?
If there's really no way you can click, you can't access Disk Utility, and I really think you have a bad OS installation. In that case, I recommend reformatting the new drive and then cloning the old one to it, since you know the OS on the old one works.
