Finally got around to using it with WD My Passport, the 1 foot cable didn't work at all, luckily the 3.3 foot cable worked fine. I don't like paying for 2 cables when only 1 works. It's hard to imagine how anyone could make a cable that doesn't work, it's not rocket science! The 3 star rating was average for the 2 cables, 1 star for the one that didn't work and 5 stars for the one that worked. Wouldn't buy again.
