I've had a second hard drive in one of those optibay things in my MBP 5,1. It's been super awesome, until it stopped getting detected today. The second hard drive is getting power and is spinning up, but is not being detected at all. I've made sure the SATA connector is on tight and even clean all the connectors with some compressed air. I swapped out the original second hard drive with another hard drive I had laying around and that one didn't get detected either. I plugged the two hard drives into a USB enclosure and they both get detected. I've also reset the PRAM and NVRAM. What can I do to fix this? Could Lion be doing something fishy? Is it the logic board? Thanks in advance for any ideas!
