If anyone is looking for a cheap CA-42 cable, try seller 'ukmobile786' on ebay. He has the CA-42 for £1.99 including UK postage and he is very quick in sending it out. I'm awaiting a T6 driver to remove the screws on my drive, so will update you later on whether I've been successful in de-bricking my STM3500320AS. The CA-42 cable I received has 3 wires only, GND, TX and RX. I've tested the cable in hyperterminal and everything looks good to go. (My cable pinout*: Red = TX, Blue = RX, Orange = GND) *Make sure you find your own cable pinout to minimise the risk of shorting anything.
