Can you still see drive in your OS? If so, try flashing the FW by using the field update tool here, http://forum.corsair.com/forums/showthread.php?t=100449. If that doesn't fix the problem, I would then find out if your SSD is still under warranty. It has a 3 year warranty, so if you are still within that period, I'd recommend that you take advantage of it and get that SSD replaced via RMA.
