I don’t know if you have solved your problem yet or not. (I am still wading through the whole thread.) I had a similar problem with my WD 500 GB portable drive too. I found a great program that has allowed me to restore my data. It is called Zero Assumption Recovery. It costs about US$50 to purchase online and you have to have another driver to save the recovered data to, but it was very easy to use. I used the “recover current data” and it found every single file… as far as I can tell. (I had over 400GB of data.) This was the best $50 I ever spent. The scan does take a very long time (almost 20 hours) but part of that might have been the processor on my labtop!! :-) I hope this helps!! Good Luck!!
