Then the drive is likely dead. If the BIOS can't see it, then recovery software won't do you any good.
Look for obvious issues like cracks in the data or power connectors. Does the drive make any spin-up sounds when power is applied? Some people here will change controller boards to try to recover the drive, some don't believe in that (like me).
Do you have data on the drive that you need? If not, and if it's in warranty, get it replaced! For free! If there's data on the drive that you absolutely need and have no backup copies of, then it's a different (and potentially expensive) story.
