Did you follow all of the standard steps to install the disk? I would double check the cables and if there is any installation software use if first. Sometimes disks ship with disk tools to partition and even format new drives.
Also, check the BIOS to make sure that the drive is coming up properly. If the bios is old, you might need an update.
The tools disk would also have some test software that you could run to verify the disk is working correctly.
