My G50V laptop I just bought has a little bit of an issue. Nothing too major but kind of annoying. I recently installed Windows 7 onto it and now the second hard drive isn't in the "my computer" area of the computer. It is although in the "Device Manager" but just isn't showing it in the my computer part of the system. I did install my drivers and everything correctly.
While I don’t have a firm answer for you, I may have found a relevant thread in the Windows 7 forums. Please follow this link and see if the information really does pertain to your situation http://bit.ly/6aFNh1 .
I hope this helps, if only to put you on the right path.
