Plextor firmware upgrade problem
 

I am trying to apply the 1.09 firmware for the PX-W8432T. After running the programs it states that this is the wrong firmware for this drive, check power and cables. The drive is correctly connected. Anyone know how to solve this? I had same issue with 1.07, but I can't remember how I got it to work.

I downloaded the file and looked at it. It seemed ok, and the only thing I can think of is it probably expects to see your original firmware version.
