Damn that sucks... I had the same problem with my 32" Samsung LCD TV when I was using a VGA cable... but after switching to a DVI-HDMI cable all was well. (IMG:

My guess is that you are experiencing the 'cant get inquiry data' error (which is being cut off by your TV) this error means that the VT6421 card is not detecting the Lite-On drive, which is causing the 'firmware validation failure' error. Try using your onboard SATA ports instead, they might work better for you. I have seen some VT6421 cards that don't detect the Lite-On drives very well.
Question - are you connecting the SATA cable first, then the POWER cable afterwards? If you connect POWER first that might be what's causing your problem... (IMG:
