Can't get blinky demo to run on nRF51822 mkit (and .hex or .bin??)

I have an nRF51822 mkit and have just tried compiling the mbed blinky demo. It compiled fine and generated a file mbed_blinky_NRF51822_.hex, which I downloaded. I have tried moving it to the device, however, and it doesn't seem to work at all. The status LED of the board just keeps blinking, and the file transfer fails.

I tried with both a file manager and using mv on the terminal, which gives output:

$ mv mbed_blinky_NRF51822_.hex /media/MBED/
mv: writing `/media/MBED/mbed_blinky_NRF51822_.hex': Input/output error
mv: failed to extend `/media/MBED/mbed_blinky_NRF51822_.hex': Input/output error

I was also expecting it to generate a .bin rather than a .hex — perhaps I have set my settings incorrectly somewhere?
