Is any of them the HD?

Under SATA Host Adapter should have your hdd. If not, then it's not detected. Either it has been disconnected by the impact and/or (I hope not) it's broken.
At this point, you should open the laptop to check if the hdd is correctly connected. If you're afraid of voiding the guarantee or something, contact the manufacturer.
