Hi, I have the same issue but it seems to affect ALL USB disks. I unfortunately only have 1 on me right now but this disk does work on Windows and I'm fairly certain that I had no USB issues in November 2013, I suspect an update in December messed things up. I have also tried with 2 other USB disks which did work previously and they also are not working.
