I had two of these 13" 2009 machines in this week, a 2.26 GHz and a 2.53. Both had defective hard drive cables. I even had problems with an optical bay hard drive adapter with the drives in place. If it will boot from the DVD with the installation disk and the hard drive disconnected, replacing the cable with a new one solved the issue on both machines. Note, two ordered used cables also failed, only the new ones worked.
