1st Gen Macbook Pro Hard Drive Clicking

1st Gen Macbook Pro Seagate 5400 RPM SATA Hard Drive replaced for a Hitachi 5400 RPM SATA Hard Drive due to constant hard drive parking resulting in clicking noise heard every few seconds. Thought hard drive was going bad but apparently this is not the case since I replaced the old hard drive with a new one. Running Tiger 10.4.11 with all updates current. Even turned off the motion sensor and hard drives still clicks. Apple have a hard drive fix only for Leopard and 7200 RPM hard drives. Apple boards say it is an overzealous power management issue. Anybody got a software fix to turn off the power management?
