What is the SATA spec of your HD's you are trying to use in this system? If you don't know can you give us the make and model of the drives. Can you boot up with the the recovery CD/DVD disk or a USB thumb drive? If you can see you can check the firmware level your system has. Refer to this Apple TN: [http://support.apple.com/kb/HT1237|EFI and SMC firmware updates for Intel-based Macs]. If your firmware is older try upgrading it and try installing the HD again.
