Hi and Welcome!
PMA failure or DMA failure? Just to be sure.
As LG drives are very picky if connected to additional IDE controllers (IDE/USB included), this might indeed be the reason for your problem.
You may try:
- replace the IDE cable by a new one, ideally an 80wired, 18" (45cm) flat ribbon cable
- setting the controller to IDE or some other non-RAID operating mode
- installing either newer drivers for the controller or try to replace them by MS standard drivers (I am not sure if such is possible, but it is wort trying).
