You might have a super smmoth one.
Disconnect the IDE cable and see if it spins with just power. And you might have a bad contact in the AMP connector or possibly a bad PS, but unlikely.
You might also check the M/B end of the cable to see if it jiggled loose while you were replacing the drive.
You can also listen to the hard drive while power is applied, should step in and out when it gets to speed.
How about trying your old drive in the machine you used to test the new one?
