Imac G5 keeps has trouble booting from new hard drive

Here is a strange one,

I needed to replace a dead hard drive in an imac g5 20. I put in a 500gb Western Digital sata drive and was able to boot from 10.5.4 retail disk that i cloned onto a firewire drive.

I was able to format and install the os.  When went to restart the machine, it could not find the drive. When I booted from the firewire drive I was able to see the start up drive.

I dug up the original 10.3 discs and follow the same process, I reformatted the disc and did a clean install of operating system

When I restarted, It did not see the drive.

I thought this was a problem with the sensor, so I ran Apple Hardware Test and Tech Tool Pro and did not find anything wrong with the memory, logic board or drive.

I have reset the PMU, reseat the ram, without any progress.

I have never seen this behavior before, I would appreciated any feedback.

Hi,

I believe this is due to the new drive being a sata 2 drive(3.0Gbps)and the G5 being a sata 1 controller. This drive is compatible with sata 1(1.5Gbps) by placing a jumper on pin 5-6. This should allow you drive to be seen on boot

if the above response does not work when you format the drive are you formatting as Mac OS Extended Journaled?
