I have a Mid 2010 MBP 17" (MacBookPro6,1) that has 2 HD's installed on it. The original Drive from apple as well as a Corsair M4 128GB SSD. The MBP was working fine and now I cannot see the SSD.

The original (non-ssd -- from now on referred to as Drive1) drive has Snow Leopard and Windows installed on it. the SSD (from now on referred to Drive2) has lion... If I try to hold down the option key when booting it sits forever and then (sometimes) eventually only displays the OS's on Drive1. If i boot into Snow leopard I cannot see the SSD at all (I used to be able to).

Any ideas on what to try?
