    That's because the drive is formatted with a Windows (Master Boot Record) Partition map.

    Load your MacOS installer DVD, hold down the "C" key and let it boot from the DVD. After you check English, stop there.

    Go to the Utilities Menu and select Disk Utility.

    In DU, click on the new drive (on the left) and then click on the Partitions tab. Change "Current" to "1 Partition" using the drop down. This will enable the "Options" button. Click on the Options button and change the Partition map to "GUID". Click Ok. Name your disk and click Apply. Quit DU and proceed with your installation or use the Utilities Menu and select a "TM restore", or shutdown and boot from a cloned drive to clone "back" to your new drive.
