If you're booting off the CD, have you gone to Disk Utility and formatted the drive?

The drive is not visible in Disk Utility

Was the other drive not present in disk utility as well?

I meant before you exchanged them...

If netiher drive could be seen, it might not be the HDD at fault, but the controller

The Hitachi disk diagnostic program told us that the drive was goosed when we tried it in anotehr machine.
