I have 3.10.24 installed too and the HDD is not recognised with that kernel either. I should perhaps add that with
kernels prior to 3.12.0, the insertion of the expresscard is only recognised if pcie_ports=native is passed to the
kernel as a parameter. Changes made at 3.12 made hot-plugging work without the parameter on this laptop.

Unfortunately, the HDD is my only USB3 device. As I said, it is detected when plugged into a USB2 port and this is the

I'm pretty sure I'm not bumping the card - none of the messages that appear when the card is purposely ejected appear in
the output from dmesg.
