Have you verified that the cables from the hard drive to the power supply and motherboard are still properly connected?

If after you check to make sure the cable going from the drive to the motherboard are connected properly; you still have the issue; its possible you could have a bad drive. But heres another thing to check for. Check the bios to see if the bios is configured to detect the second drive. Technically the second drive should be automatically detected by the bios; but if its not and you already have checked the cables etc.; it sounds to me like you could have some sort of hardware issue with the drive itself.
