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.

This is a major issue for me as I can only access my Ubuntu machine via
